[MOAB-dev] Disable fortran in moab-5.0.0

[Vijay S. Mahadevan]

We used to have Eigen as a required dependency, and many of users
didn't specifically like this (especially distributing our own copy of
Eigen causing header/version conflicts). Its much easier to impose
BLAS/LAPACK as a dependency since on 90% of all machines, the
libraries are available, and now Eigen is an optional dependency. The
only downside is that the symbol is indecipherable without a proper FC
compiler. We can try something less rigorous like grepping the symbol
table of the library etc. If this is a very hard restriction, I can
look into doing a different configure check for the BLAS symbols.

Will keep you updated.
