Hi Guix,

with this patch applied I can build randomjungle without having to add
the “lib” output of gfortran to the package inputs.

This is related to the changes I pushed in commit 82f145e to fix
bug#19733, which seems to have broken the build of randomjungle and
slepc, among others.

Is this acceptable?  Should we do this for all gfortran variants then?
