Update GCC_DEFAULT from 9 to 10.

A few (mostly Fortran-based) ports need to be patched because GCC 10
is stricter.  A handful of ports need to be restricted to GCC 9 because
they fail with 10.

5 ports still fail with GCC 10.  However, seeing as this work has been
ongoing since 2020-05-24, it is simply time to make the commit and
notify the affected maintainers.

While here, pet portlint (Makevar order).
