Apply patch from Scott Bambrough <scottb@corelcomputer.com>
  Modified arm*-*-linux-gnu* target to set thread_file to 'posix' if
  --enable-threads, --enable-threads=[yes,pthreads,posix] is passed as a
  command line parameter to configure.
  Modified TARGET_LIBGCC2_CFLAGS to include -fPIC.  If not included libgcc2
  is not compiled with PIC flag, as it should be.
