x86: Properly set x86 minimum ISA level [BZ #31883]
Properly set libc_cv_have_x86_isa_level in shell for MINIMUM_X86_ISA_LEVEL
defined as
(__X86_ISA_V1 + __X86_ISA_V2 + __X86_ISA_V3 + __X86_ISA_V4)
Also set __X86_ISA_V2 to 1 for i386 if __GCC_HAVE_SYNC_COMPARE_AND_SWAP_8
is defined. There are no changes in config.h nor in config.make on x86-64.
On i386, -march=x86-64-v2 with GCC generates
#define MINIMUM_X86_ISA_LEVEL 2
in config.h and
have-x86-isa-level = 2
in config.make. This fixes BZ #31883.
