Some distro may ship dangling symlinks in include directories, triggers
the access failure. Skip it and continue to next header instead of
being to panic.
Restore to old behavior before r12-5234 but without resurrecting the
problematic getcwd() call, by using the environment variable "INPUT"
exported by fixinc.sh.
Tested on x86_64-linux-gnu, with a dangling symlink intentionally
injected into /usr/include.

* fixincl.c (process): Don't call abort().
POSIX says:
On some implementations, if buf is a null pointer, getcwd() may obtain
size bytes of memory using malloc(). In this case, the pointer returned
by getcwd() may be used as the argument in a subsequent call to free().
Invoking getcwd() with buf as a null pointer is not recommended in
conforming applications.
This produces an error building GCC with --enable-werror-always:
../../../fixincludes/fixincl.c: In function ‘process’:
../../../fixincludes/fixincl.c:1356:7: error: argument 1 is null but
the corresponding size argument 2 value is 4096 [-Werror=nonnull]
It's suggested by POSIX to call getcwd() with progressively larger
buffers until it does not give an [ERANGE] error. However, it's highly
unlikely that this error-handling route is ever used.
So we can simplify it instead of writting too much code. We give up to
use getcwd(), because `make` will output a `Leaving directory ...` message
containing the path to cwd when we call abort().

This fixes an ODR violation in the AIX headers that is detected by C++
modules. While unnamed structs with typedef names for linkage
purposes are accepted, this case is an anonymous struct without such a
typedef name -- the typedef is attached to the pointer-to-struct type.
Fixed by naming the struct.

AIX protects the STDC Format Macros in a manner that can prevent the
definition of the macros depending on the order of header inclusion.
The protection of the macros was referenced in C99, removed in C11, and
never specified in any C++ standard. Also, the macros are in the namespace
reserved to the implementation (compiler) so the compiler is permitted to
choose to inject those names.

mkheaders.in uses substitutions of @SHELL@ to run fixinc.sh and
mkinstalldirs. Problem is, SHELL comes from CONFIG_SHELL for the
build system, and it needs not match whatever is available at an
unrelated host system after installation, when mkheaders is supposed
to be run.
I considered ditching the hardcoding altogether, but decided to retain
it, but allowing CONFIG_SHELL and SHELL to override it, if any of them
can successfully run mkinstalldirs, and if those and the substituted
@SHELL@ fail, fallback to /bin/sh and to plain execution of the
script, which appears to enable at least one shell on a system that
doesn't typicall have a shell to recognize a script by #!/bin/sh and
reinvoke itself to run it.
If all of these fail, we fail, but only after telling the user to
retry after setting CONFIG_SHELL, that fixincl itself also uses.

Some system headers can be broken by the machine_name fix performed
by GCC during the fixincludes step. According to the comment in
fixincludes/fixinc.h:130 :
On some platforms, machine_name doesn't work properly and
breaks some of the header files. Since everything works
properly without it, just wipe the macro list to
disable the fix.
So we can just skip it to avoid trouble.

* fixinc.in: Skip machine_name fix on powerpc*-*-linux*.
vxworks7 headers haven't required fixes, and we've decided to avoid
running fixinc on them.
The problem with that is that, with a dummy fixinc, mkheaders wipes
out include-fixed but then multi_dir subdirs are not created again, so
we end up with a limits.h named after each multi_dir, when there are
non-default multilibs. Oops.
This patch arranges for a dummy fixinc to be created for *-*-vxworks7*
targets, and fixes mkheaders so as to create multi_dir subdirs in
include-fixed after wiping them out, and to copy limits.h so that it
won't take the name that should be of a subdir (unless the multi_dir
is limits.h, but that's hopefully never the case ;-)
for fixincludes/ChangeLog
* mkheaders.in: Re-create subdirs, copy limits.h into subdir.
* mkfixinc.sh: Create dummy fixinc for *-*-vxworks7*.
There is no reasonable chance that the SDKs in question will be re-
issued, so the only viable solution is a fixincludes.

Darwin has had long long functions for some considerable time and these are
exposed in Darwin8 and Darwin11+ headers. However, for some reason it was
elected to hide them behind __STRICT_ANSI__ and __STDC_VERSION__ on Darwin9
and Darwin10. This is a problem for G++/libstdc++ that expects the functions
to be available for strict ansi (-std=c++14, for example) and without
defining __STDC_VERSION__. The fix here follows the pattern used in
Darwin11+ headers where the functions may be explicitly hidden by defining
__DARWIN_NO_LONG_LONG.
This fixes the tr1 testsuite fails seen on Darwin9 and 10.
