The test results don't inspire me with confidence.  A lot of the fails
are due to targets not supporting -mlittle-endian, but there are other
fails that show the patch series needs more work before it is ready
for review.  Also, please don't write tests that require one
particular endianness.  Write the objdump match patterns to suit both
endians instead.  Something like this:
