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.
