 This is the native one, please check your 'libc.so' script
for the 'powerpc-linux-gnu' target. Basically you should have
edited it after installing it on the cross-host. Just remove
all absolute paths from the 'GROUP' definition...

	/* GNU ld script
	   Use the shared library, but some functions are only in
	   the static library, so try that secondarily.  */
	GROUP ( libc.so.6 libc_nonshared.a )

 The 'sys-include' is a weird place for the target headers,
please use the standard 'include'...

 And you should have ALL libs in the 'lib', not only the '.a'
ones and the 'lib*.so*' ones, but the 'ld.so.1' too... And
have done quite a lot work with rearranging the symlinks...

Cheers, Kai
