[Patch, libgomp, testsuite] add libgfortran.spec.

[IainS]

This will allow fortran  libgomp tests to use libquadmath when  
required (I'm told none do yet).
.. but it will also ensure that, if the libgfortran.spec includes  
substitutions, they are available in the testsuite.

checked (in conjunction with http://gcc.gnu.org/ml/fortran/2010-11/msg00348.html) 
  that the static lib substitution occurs properly for i686-darwin9.

OK for trunk (with a proper Changelog, of course)?
