Misleading error message from gas/configure.tgt for generic a.out

[Gunther Nikl]

Hello!

When I tried to build binutils-2.20 for m68k-aout, the build process
died configuring gas. The error message given is:

  "This target is no longer supported in gas"

The reason configure.tgt complains is that bfd_gas is not set to true.
I am aware that generic m68k-aout used to be a non-bfd assembler, but
since support for non-bfd assembler was removed in 2005, I expected
that those cases would now silently build a BFD assembler. What am I
missing here?

I had to tweak configure.tgt. However, I think there should be a
configure knob to set bfd_gas to true to make cases like generic
a.out work without diving into the config files.
