If GNU ld worked well enough to turn in good testresults on a gcc run,
I'd support turning it on, but...

This is 4/10 of the failures you describe.  I don't know what this
means.  There is a basename command in /bin.

There's the rub and, I suspect, the dealbreaker.  OpenServer's libraries
are wierd.  I can't recall the details, but I seem to remember them
containing both ELF and COFF objects in the archives and the native
linker knowing how to sort that all out.

This probably means it's emitting an incorrectly formed binary.

Failing 2/3 of the tests sounds pretty serious to me.  Does it seem to
work "well enougn" in the real world?

So even though we finally gave up on GCC supporting both COFF and ELF
and that's probably enough to make GAS viable on this target, the linker
still gets exposed to system facilities that have both and I don't know
that it won't be blinded by that light.  Maybe it can be taught to cope;
maybe it already has been.
