It could compare build-ids, for example.

If there are no build-ids, it may fall back to comparing file contents as you
suggested.

That would work, too.

I didn't want to suggest turning off or ignoring warnings in our test
suite, though.  I don't think that's generally a good idea.

I'd rather make gdb_simple_compile use standard_output_file if we agree
that exec-file-mismatch shouldn't be changed and that this should be handled
in the test suite.
