(via Mk/bsd.default-versions.mk and lang/gcc) which has moved from
GCC 5.4 to GCC 6.4 under most circumstances.
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c++11-lib, c++11-lang,
c++14-lang, c++0x, c11, or gcc-c++11-lib.

CalculiX has alwasy been comoposed of two independent packages: ccx and
cgx. Ccx, the main tool for doing FEA, depends on fortran and currently
has to be built with GCC. Cgx, on the other hand, uses OpenGL and the C++
libraries it depends on are built with our native clang so buuilding it
with GCC causes C++ library conflicts.
By making ccx an independent port we can better focus on the specific
requirements of each tool and avoid compiler-related conflicts. This also
helps the port work again with newer versions GCC.
