I don't like this.  There are quite a lot of generic gas tests that
fail if you define TC_WANTS_ERROR_SUMMARY.  So they will at least need
modifying, and likely duplicating, to suit two possible gas error
behaviours.

If you really think this summary output is desirable, then you will
think it worth spending your time fixing the gas testsuite.  On all
targets.  Anything less is just pushing the job onto Nick, me, or
some other global maintainer since most targets don't really have
active maintainers.

I'm more inclined to recognize we currently have some dead code in
write_object_file and just delete it.
