[svn-r11418] Purpose:

Bug fix/feature

Description:
Disabled shared libraries for a number of Fortran compilers that don't
support them.
This allows other compilers to support shared Fortran libraries.

Solution:
Added a conditional, SHARED_FORTRAN_CONDITIONAL, which is true if
Fortran supports shared libraries.  It is set in configure.in.

Platforms tested:
mir, sleipnir, colonelk, heping
