Does anybody know if POSIX semaphores have been ported to ppc_6xx, and
if so, where I could find a binary copy?

This normally works in every modern glibc. Maybe you were using an
set of kernel headers that is too old. Make sure that you have
up-to-date version of both kernel and glibc and that you use the
kernel header files you get from 'make headers_install' in the kernel.
