Was this run through the testsuite on any particular architectures?

On mips-elf, using sources updated this morning, comparing against
sources updated about a week ago, there are new failures:

FAIL: readelf -h
FAIL: readelf -S
FAIL: readelf -s
FAIL: readelf -r

And all of them go like:

extra lines in readelf.out starting with "^There are no unwind sections in this file.$"
