Nope.  --target=z80-unknown-coff.  Knowing the target triple is one of
those things you just have to know for cross toolchains, unless you
are willing to poke through various configure scripts like
gas/configure.tgt.

With most targets you can use contractions like --target=z80-coff, but
this doesn't work for z80 since the top level config.sub doesn't know
anything about z80.  Fixed as follows.  Ben, can you add this to git
config sources?
