[uClibc] uclibc-gcc using wrong libraries when compiling?

Scott,
	Assuming PowerPC uses an ELF format (I've _never_ used Linux on
PPC, so I have no idea)...you can always use the tool "readelf" to read
the compiled file, and find what libs it's linking to.  I don't know how
well this would work if you're native arch isn't PowerPC, as the
endianness would be incorrect.  Either way, it would seem that all the
compilers, etc are in proper at a _very_ first glance.

Keep us Posted (tm)
