In order to accomodate usage of either pthreads implementation, we now

have to create symbolic links for 'semaphore.h' and 'pthread.h' which
will point to the proper pthreads directory. When we finish getting
NPTL working with uClibc, perhaps we can merge them, but a first glance
at the differences between the two does not make that very likely.
