Ok, I'll post another patch shortly.

Yes, I understand. But it still seems correct to cleanly separate
the targets so that one day you'll be able to specify precisely which
ones you want.
(Even without my patch, you can't properly cross debug both Linux and
NetBSD PowerPC binaries in the same gdb, because the Linux cross debug
stuff is incomplete.)
So, yes, one day I want to be able to say:
--target=powerpc-unknown-netbsd,powerpc-unknown-linux-gnu
...or whatever, and have the right thing happen, all based on the
markers in the debugged executable that the gdbarch_osabi_*() stuff
can examine (the osabi stuff will even warn you if you try to debug
an executable which requires OS ABI support not compiled into GDB).
