Problem:
When linking the executable with -lC or -lpthreads the linker (GNU ld version
2.16 complains:

/usr/lib/../lib32/libC.so: undefined reference to `_mpi_sgi_init'
/usr/lib32/libpthread.so: undefined reference to `_mpi_sgi_init'

This makes compiling a lot of programms impossible. , (Qt and Motif for example,
but also gdb).
