#     selftests/powerpc: Only test lwm/stmw on big endian
#     
#     Newer binutils (>= 2.36) refuse to assemble lmw/stmw when building in
#     little endian mode. That breaks compilation of our alignment handler
#     test:
#     
#       /tmp/cco4l14N.s: Assembler messages:
#       /tmp/cco4l14N.s:1440: Error: `lmw' invalid when little-endian
#       /tmp/cco4l14N.s:1814: Error: `stmw' invalid when little-endian
#       make[2]: *** [../../lib.mk:139: /output/kselftest/powerpc/alignment/alignment_handler] Error 1
#     
#     These tests do pass on little endian machines, as the kernel will
#     still emulate those instructions even when running little
#     endian (which is arguably a kernel bug).
#     
#     But we don't really need to test that case, so ifdef those
#     instructions out to get the alignment test building again.
