[PATCH] [tree-ssa] [gfortran] update testsuite/lib/gfortran.exp for LD_LIBRARY_PATH part

[Andrew Pinski <pinskia at physics dot uc dot edu>]

This is just a sync from g++.exp for the LD_LIBRARY part of 
gfortran.exp.
This also fixes the testsuite on Darwin to find the shared library and 
some
other targets too.

OK?

Thanks,
Andrew Pinski
