I am trying to build the trunk version of gcc to have Cilk on OpenBSD.

I attach three changes to libcilkrts.  Two changes treat OpenBSD like
FreeBSD.  One change is needed because OpenBSD defines PTHREAD_MUTEX_* as
enumerations rather than preprocessor constants.

That doesn't seem to be the autoconf'esque way to do this:
better would be to have a configure check for this somewhere and then
test the results.
