AIX_WEAK_SUPPORT

AIX_WEAK_SUPPORT

[Alan Modra]

Making target code depend on a host define like _AIX52 is never
correct, so out it goes.  Also, sort some config.bfd entries a little
to make it more obvious there is a config difference between aix5.1
and aix5.2.  These two changes should make no difference to anything
in binutils.  The gas define of AIX_WEAK_SUPPORT on the other hand was
wrong, so fix that.  Finally, fix some testsuite fails on aix < 5.2 by
simply not running the tests.

include/
	* coff/internal.h (C_WEAKEXT): Don't depend on _AIX52.
bfd/
	* coffcode.h (coff_slurp_symbol_table): Don't depend on _AIX52.
	(coff_classify_symbol): Likewise.
	* config.bfd: Sort some entries.
gas/
	* configure.ac (AIX_WEAK_SUPPORT): Don't set for aix5.[01].
	* configure: Regenerate.
	* testsuite/gas/ppc/aix.exp (xcoff-visibility-1*) Don't run
	for aix < 5.2.
