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

"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.

alpha-dec-vms always loads a number of libraries, -limagelib,

ERROR should really be reserved for errors in the testsuite framework,
not just normal errors from the tools under test. Removing use of
perror has been suggested before but without action, over concerns
that some test failures might be missed. This patch removes uses of
perror in ld_assemble, ld_compile and ld_nm, and updates numerous
places that ignored the result of these functions by inappropriately
returning an "unresolved" test status. Net result over my large set
of targets look good, in some cases improving the diagnostics, eg:
i386-msdos -ERROR: tmpdir/script: nm failed
i386-msdos -ERROR: tmpdir/script: nm failed
i386-msdos -ERROR: tmpdir/script: nm failed
i386-msdos -ERROR: tmpdir/script: nm failed

Fix an issue with the SEGMENT_START builtin function where its result is
absolute when taken from the default supplied, and section-relative when
taken from a `-T' command-line override. This is against documentation,
inconsistent and unexpected, and with PIE executables gives an incorrect
result with the `__executable_start' symbol.
Make the result of SEGMENT_START always section-relative then.

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.

This patch fixes PR 4643 by allowing symbols in the LENGTH and ORIGIN
fields of MEMORY regions. Previously, only constants and constant
expressions are allowed.
