    Darwin, PPC, testsuite, backport fix for bmi2-bzhi64-1a.c
    
    This test is failing with older cpus because the included header needs both
    altivec and vsx to be enabled to succeed in compiling. Without this (if these
    are not defaults for the cpu) there are errors like:
    
    In file included from ... x86intrin.h:41,
    from ... bmi2-bzhi64-1a.c:6:
    ... xmmintrin.h: In function '_mm_loadu_ps':
    ... xmmintrin.h:122:11:
    error: incompatible types when returning type 'int' but '__m128' {aka '__vector(4) float'} was expected
    <snip>
    ... xmmintrin.h: In function '_mm_cvtps_pi32':
    ... xmmintrin.h:996:3:
    error: use of 'long long' in AltiVec types is invalid without '-mvsx'
    <snip>
    
    Fixed by adding -maltivec -mvsx to the options
