Jeff Squyres 7136dbb5b3 Fixes trac:3523. Discussed on the OMPI weekely teleconf today: add a
configure test to ensure that the Fortran compiler supports BIND(C)
with LOGICAL parameters (per
http://lists.mpi-forum.org/mpi-comments/2013/02/0076.php).

This may become moot shortly -- Pathscale tells me that they intend
upgrade their compiler to support BIND(C) with default LOGICAL in the
very near term (this week?).  But we still want this configure test so
that Open MPI won't even try to build the F08 bindings with older
versions of the Pathscale compilers (or any compiler that doesn't
support BIND(C) and LOGICAL parameters).

This commit was SVN r28110.
