No specific fixing needed: FWIW, it "works for me", at least for
ELF and a.out, though I'm not sure (nor do I care) how good the
a.out quality is.  Anyway, I don't want to be the only user of
brittle machinery that I don't actually need.

Yes, a there has to be lots of e.g. "OUTPUT_FLAVOR ==
bfd_target_elf_flavour" in the target macros.

So, can I take that as an indication that you officially support
removing it?
