No. The linker doesn't include absolute path's in the binaries.

Compile as usual using the toolchain for powerpc. It's up to the
dynamic linker (ld.so) to find the needed libraries, which it
searches for in some pre-defined directories, /lib is one of
them. You can alter that search path with LD_LIBRARY_PATH.

Depending on how the toolchain works, you may need to alter the
path for the dynamic linker which is stored as an absolute path
in the binaries. You do this by passing the -Wl,dynamic-linker=
to gcc.
