What version are you using?
Hopefully this will work. I think someone did something similar EONS ago
(3.5.1?) on a Mac targetting a 60x.

Hopefully someone else can handle this one.
I do know that the DWARF standard used by binutils does not contain
the extensions used by other commercial implementations. So debugging
information from an ELF GNU tools executable may not be recognized by
something like an emulator or another debugger.

newlib 1.8.0 to avoid this during configuration.

There are others working the ppc860 so one of them will probably jump in.
