Cleanup LIB_DEPENDS

Remove # $FreeBSD$ from Makefiles.

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).

science/elmerfem: Update to 8.4.20200708 and fix dependencies

* Update to commit 679a882b on the devel branch (after elmerice merge + fixes)
* Removed DISTVERSIONPREFIX; we use the devel branch now, not official releases
* Removed Tcl dependency; this was only used for ElmerPost, which is obsolete
* Moved lots of library dependencies that were only needed for OpenCASCADE
* Added OCC option for OpenCASCADE dependency; on by default.
* Fixed indirect dependencies (Python 2.7 -> 3.7 and VTK 6.2 -> 8.2)
* Moved WITH_QT5 and QT_FOUND to GUI_CMAKE_ON to avoid CMake warnings
* Added QT5_LIBS to avoid lines longer than 80 characters in the Makefile
* Removed the partial f02cb33a patch file, which is no longer needed
* Removed the last sentence in pkg-descr (written for science/elmerfem-devel)
* Added HelmholtzProjection.so and SpringAssembly.so to pkg-plist
