 Yes, the 'powerpc-eabi' target defines only the object format, calling conventions
etc., not a target board or a simulator or a opsys or anything for which you could
create real executables. If you use the '-v' option in CFLAGS, you will see that it
doesn't include any startups (crt*.o), any C-library (-lc) or any glue-library for
some supported target board (e.g. '-lads') into the link command...

 The workaround you will see in the nice GCC-manual, "Invoking / Sub-targets / PowerPC"
or something. You can use any of the supported PowerPC/EABI targets while building (for
which to create the 'dummy'-executable), the results for libiberty and libstdc++ are
always the same.

Cheers, Kai
