I got it to work after playing around 'patch -p X' with
a few different variants of X.
Unfortunately, there are still a large number of failures.

This is due to not linking in libpthread. On FreeBSD, to
include pthread, one needs to add the -pthread option or
have a spec file that magically includes or do whatever
gomp does. With -fopenmp, -pthread is included. Here's
an example:
FAIL: gfortran.dg/coarray/alloc_comp_1.f90 -fcoarray=lib
-O2 -lcaf_shmem (test for excess errors)
