[Rd] R 2.1 and gfortran

The reasons why it is not there *are* in the R-admin manual.  This was
deliberate: we do not include known broken tools in the searches.

Once gcc-4.0.1 is released and commonly used it will be safe to add it,
but not before. (That will most likely be for R-2.2.x, not R-2.1.x.) For
example, the current gfortran in FC3 is pre-4.0.0 and does not work (and
cannot be made to work on AMD64), and Simon Urbanek found an Apple version
of 4.0.0 that did not work.
