[bug#38636] Rationale

[Konrad Hinsen]

For those wondering why I submit this patch: I think "gfortran" should
be a hidden package for exactly the same reasons that "gcc" is a hidden
package. What users should see and install is "gfortran-toolchain", not
"gfortran", and having both show up in a package search only creates
confusion.

Cheers,
  Konrad.
