It is not, however `config.status' itself is, and with the change I made
it depended on `libbfd.la' because one of the autoconf tests did. So if
e.g. you ran `configure' in opcodes/ first (for whatever reason), then
running `make' there would run `configure' and then `make' in bfd/ because
of other dependencies, however `config.status' would not get updated in
opcodes/ afterwards, before its targets were made.

Thanks, Alan, for sorting this out in my absence!
TBH I think `distclean' shouldn't really depend on non-phony targets in
the first place, or at least it should ignore errors in their re-creation,
but there you go. With releases upcoming it's no time now to revamp our
