Add explicit link to libpthread, to work around debugging issues

When debugging through a call to exec, gdb would report thread errors:

  Warning: couldn't activate thread debugging using libthread_db:
           Cannot find new threads: generic error

Similar errors were reported by:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=579021

Adding an explicit link to libpthread in the test applications
improved the debugability of fips when run with the unit tests.
