Thats an existing thing to help indicate 'be' versus 'le'.

altivec-7-be.c:/* { dg-do compile { target powerpc64-*-* } } */
altivec-7-le.c:/* { dg-do compile { target powerpc64le-*-* } } */

but yeah, we are potentially missing coverage for -m32. 

Should I instead try to combine the le,be tests, and set target markers
on any le/be unique scan-assembler stanzas?
