Subject: [PATCH] freecad: fix for devshell

Linking with `gfortrun.cc.lib` instead of `gfortrun.cc`. For unknown
reason previous variant works well withing sandbox. But there was an
issue with building freecad in development shell. The
`${gfortran.cc}/lib` does not contains shared (.so) variants of
libraries but static archives (.a). This leads to invalid linking of
shared library with static archive which was not compiled with `-fPIC`.
