I've now tried that and it still produces rs6000:6000.  The only place I
see rs6000:6000 in bfd is in cpu-rs6000.c which makes me think there
must be some tie between coff-rs6000.c and the default architecture
that I don't have a clue about.  

Here is what I know about what is expected based upon the examining
headers of old toolset objects and executables:

 + for .o's,   architecture=rs6000:6000,    flags=0x031
 + for .exe's, architecture=powerpc:common, flags=0x133

The new toolset has it mostly correct:

 + for .o's,   architecture=rs6000:6000,    flags=0x031
 + for .exe's, architecture=rs6000:6000,    flags=0x133

Somehow, I need to tweak something to get the default architecture
for exe's to be powerpc:common.  I'm hunting, but I can't find
the right thing. :(  Any more ideas?
