[PATCH] OpenMP flags are disregarded by libtool in library link mode

Included is a patch to fix an issue where OpenMP flags are discarded by libtool.

This has popped up a couple of times.  For example,

Following that last link, my understanding is that OpenMP flags like
-fopenmp need to be preserved like a pthread flag is.  Also following
that last link, the patch works by appending OpenMP flags to the list
of pthreads flags appearing twice within ltmain.m4sh.  The OpenMP flag
list was lifted from FFTW's AX_OPENMP macro.

I wasn't sure of the exact ChangeLog content necessary per
http://www.gnu.org/software/libtool/contribute.html.  The commit
message is suitable for insertion into the ChangeLog, I think.
