Fix linking of omp_foreign_thread_team_reuse test

[dim]

Summary

On FreeBSD, linking the misc_bugs/omp_foreign_thread_team_reuse.c test
case fails with:

/usr/local/bin/ld: /tmp/omp_foreign_thread_team_reuse-c5e71b.o: undefined reference to symbol 'pthread_create@@FBSD_1.0'

This is because the program is linked without -lpthread. Since the
%libomp-compile-and-run macro does not allow that option to be added to
the compile command line, split it up and add the required -lpthread
between %libomp-compile and %libomp-run.

[dim]

Scratch this, ran arc in the wrong repo. Sorry.
