Something along these lines:

Don't know whether that interferes / is consistent with the `SAGE_FORTRAN`
variable and/or the odd `sage_fortran` script (which should IMHO get
removed anyway).
Setting / overriding `OBJC` etc. may not be necessary at the moment, but
certainly would make sense, too, if we build compilers for more languages
(as is currently the case with the GCC 4.7.x spkg).
