Thanks landry@ for the bulk:

All give the same error:
eg++: error: -fuse-linker-plugin is not supported in this configuration
Maybe someone with more knowledge sees the error as spots the problem
right away...

Anyways, I really don't know much about powerpc and I'm short on time this days.
Should I flag this as:
NOT_FOR_ARCHS = powerpc
?

Cheers.
Elias.
