Since there's no conflict with versions in base, it seems helpful to
install a symlink so that you can just run 'gfortran' rather than
needing 'egfortran'. More useful for people compiling things themselves
rather than for use in ports. (Amongst others, this helps if building
Python software in a venv, e.g. using pip/pipx/etc, when it has Fortran
code to compile).

ok?
