rs6000: float128 on BE and 32-bit · 7502c597

This fixes float128 on BE and on 32-bit.

The configure tests need to use -mabi=altivec for 32-bit, since it is
not the default there.  That also enables the "vector" keyword, used by
the tests.  To do this it temporarily adds a few flags to the CFLAGS
variable.

It also fixes a syntax error in the libgcc_cv_powerpc_float128_hw test
(the function name was missing in the function declaration).

Regenerating config.in (via autoreconf) removed the duplicate definition
of HAVE_SOLARIS_CRTS.

Finally, this adds a "-mfloat128-hardware requires -m64" test to
rs6000.c: all the current patterns need 64-bit registers.  Maybe we'll
want to add float128 hardware support to 32-bit some day, but certainly
not today.


	* config/rs6000/rs6000.c (rs6000_option_override_internal): Disallow
	-mfloat128-hardware without -m64.

libgcc/
	* configure.ac (test for libgcc_cv_powerpc_float128): Temporarily
	modify CFLAGS.  Add -mabi=altivec -mvsx -mfloat128.
	(test for libgcc_cv_powerpc_float128_hw): Add -mpower9-vector and
	-mfloat128-hardware to the CFLAGS.  Fix syntax error in the C snippet.

[libstdc++-v3] Fix detection of obsolete isnan · 74106ead

libstdc++-v3 configure checks whether old glibc inline definitions
of isnan would conflict with the libstdc++-v3 definitions and
works around them if so.  But if g++ 6.x build A is used to build
another g++ 6.x B, the configure step for B will pick up the math.h
installed alongside A instead of the glibc version.  configure will
then assume that the workaround isn't necessary, leaving B with a
broken cmath.

isinf already worked around this.  This patch extends the same fix
to isnan.  (Thanks to George for the fix.)

	* acinclude.m4 (glibcxx_cv_obsolete_isnan): Define
	_GLIBCXX_INCLUDE_NEXT_C_HEADERS before including math.h.
