selftests/powerpc: Skip tm-trap if transactional memory is not enabled
Some processor revisions do not support transactional memory, and additionally kernel support can be disabled. In either case the tm-trap test should be skipped, otherwise it will fail with a SIGILL. Fixes: a08082f8e4e1 ("powerpc/selftests: Check endianness on trap in TM") Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
