Description:
* This patch removes -mvsx and -maltivec for go aix/ppc.
These options don't seem compatible with Go stack layout.
Tests:
* AIX 7.2: Configure/Build: SUCCESS
Changelog:
* config/rs6000/aix71.h (SUBTARGET_OVERRIDE_OPTIONS): Remove OPTION_MASK_VSX
and OPTION_MASK_ALTIVEC from rs6000_isa_flags with Go on 32 bits.
* config/rs6000/aix72.h (SUBTARGET_OVERRIDE_OPTIONS): Likewise.
