Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.
Catch "exec $CC_FOR_TARGET" won't use the gas/ld that we just build,
and in fact run_host_cmd_yesno is a better choice for it.
ld/ChangeLog:
* testsuite/ld-elf/indirect.exp: use run_host_cmd_yesno
instead of handwrite catch exec $CC_FOR_TARGET.
Currently, the var run_tests is defined by syntax {{}},
while in this case, variables cannot be used.
Thus $NOPIE_CFLAGS and $NOPIE_LDFLAGS are passed to cmd as names
instead of values:
gcc ... $NOPIE_CFLAGS -c .../indirect5a.c -o tmpdir/indirect5a.o
Let's use [list [list ]] syntax instead.
ld/ChangeLog:
* testsuite/ld-elf/indirect.exp(run_tests): use [list [list]]

The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
The top level Makefile, the ld Makefile and others, define
CC_FOR_TARGET to be a compiler for the binutils target machine. This
is the compiler that should be used for almost all tests with C
source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS
too. This was all supposed to work with the testsuite .exp files
using CC for the target compiler, and CC_FOR_HOST for the host
compiler, with the makefiles passing CC=$CC_FOR_TARGET and
CC_FOR_HOST=$CC to the runtest invocation.
One exception to the rule of using CC_FOR_TARGET is the native-only ld
bootstrap test, which uses the newly built ld to link a copy of
itself. Since the files being linked were created with the host
compiler, the boostrap test should use CC and CFLAGS, in case some
host compiler option provides needed libraries automatically.
However, bootstrap.exp used CC where it should have used CC_FOR_HOST.
I set about fixing that problem, then decided that playing games in
the makefiles with CC was a bad idea. Not only is it confusing, but
other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp.
So this patch gets rid of the makefile variable renaming and changes
all the .exp files to use the correct _FOR_TARGET variables.
CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will
correct bootstrap.exp to use CFLAGS, and a number of other things I
noticed.

"unresolved" as a test result means runtest returns an error, which
can be confusing when there is no apparent error unless you look in
.log files. In particular many tests are skipped without reporting an
error if no target C compiler is found, but if a target C compiler is
found but won't compile a testcase for some reason we used to mark the
test as unresolved. Which is no more worthy of an error than when
lacking a C compiler entirely.

This patch is a result of noticing messages like the following:
tmpdir/tls32.o: in function `_start':
(.text+0x1c): unresolvable R_PPC_REL24 relocation against symbol `__tls_get_addr_opt'
./ld-new: final link failed: symbol needs debug section which does not exist
The "needs debug section" comes from attempting to use debug info to
find source line information to print the first error message. That
error isn't of interest to the user, and any previous bfd_error value
which might be of interest is overwritten. So save and restore
bfd_error around the fancy error reporting code.
That still doesn't leave us with a clean bfd_error. Now we get
./ld-new: final link failed: nonrepresentable section on output
An unresolvable relocation surely doesn't mean there is some bfd
section that ld doesn't know how to output! Digging into that showed
a _bfd_elf_section_from_bfd_section failure attempting to find an elf
section correcsponding to ".interp". So don't go looking for elf
sections on linker created bfd sections.
And then fix the linker testsuite which expected the bogus message..
bfd/
* elflink.c (elf_fixup_link_order): Don't attempt to find
an elf_section for linker created bfd sections.
ld/
* ldmisc.c (vfinfo): Save and restore bfd_error around bfd
function calls that might set it.
* testsuite/ld-elf/indirect.exp: Don't expect "nonrepresentable
section" message.
The ld testsuite includes numerous tests that depend on being able to
compile and link programs with the C compiler. Some of these tests
use [which $CC] to check for the presence of the compiler before
proceeding with the test, but run_ld_link_exec_tests and run_cc_link_tests
give ERRORs if compilation fails. Also, even if $CC is defined and present,
it may not be usable due to missing libraries, etc.
This patch adds a new procedure check_compiler_available that attempts
to build an empty program and caches the result. Uses of [which $CC]
are replaced with calls to this procedure, and run_ld_link_exec_tests
and run_cc_link_tests now also guard attempts to use $CC.

GOT reference to global symbol in PIE will lead to dynamic symbol. It
becomes a problem when "time" or "times" is defined as a variable in
an executable, clashing with functions of the same name in libc. If

Many of the ld tests are not run for cross builds, in some cases
because the test needs to run a newly linked executable, and in others
simply because it was easier to write the test for native only. Even
when a test needs to run, it's good to compile and link to exercise
the linker. So that's what this patch does. I've also rid us of
the old ld_link procedure with all the HOSTING_CRT0 etc. setup. It's
much simpler to just link with $CC.
This does mean that a cross build with cross-compiler installed but
no cross C-library will give lots of failures. If that turns out to
be too annoying, I guess we can write a tcl procedure to detect it and
not run all the extra tests.

The hidden versioned symbol can only be merged with the versioned
symbol with the same symbol version. _bfd_elf_merge_symbol should
check the symbol version before merging the new hidden versioned
symbol with the existing symbol. _bfd_elf_link_hash_copy_indirect can't
copy any references to the hidden versioned symbol. We need to
bind a symbol locally when linking executable if it is locally defined,
hidden versioned, not referenced by shared library and not exported.
