Teach the linker that __mcount_internal, __sigjmp_save_symbol,
__syscall_error and __GI_exit do not use r2, so that it does not need to
recover r2 after the call.
Test at configure time if the assembler supports @notoc and define
USE_PPC64_NOTOC.
This feature doesn't depend on the linker, as can be seen from the
actual test. It's a compiler feature.
* sysdeps/powerpc/powerpc64/configure.ac: Correct "linker support
for overlapping .opd entries" to "support...".
* sysdeps/powerpc/powerpc64/configure: Regenerate
With AIX port deprecated there is no need to check/define
HAVE_ASM_GLOBAL_DOT_NAME anymore since the current minimum binutils
supported (2.22) does not emit global symbol with dot.
This patch removes all the HAVE_ASM_GLOBAL_DOT_NAME definition and
checks for powerpc64 port.
Autoconf has been deprecating configure.in for quite a long time.
Rename all our configure.in and preconfigure.in files to .ac.
