Essentially replace (or rather reinvent) the lang/gcc port, which more

or less ended up identical to lang/gcc5 now that we differentiate between
lang/gccX-devel and lang/gccX ports, by (or as) a meta-port that pulls in
the respective lang/gccX port (based on the setting of $GCC_DEFAULT) and
defines gcc, g++, and gfortran as symlinks to the respective versioned
binaries.

This is the end of a long journey establishing this infrastructure
which is now similar to the one of the python ports, for example,
and makes upgrading the default as well as adjusting the default
locally a lot easier.

(PORTVERSION remains at 5.4.0 for now to avoid PORTEPOCH, but
PORTREVISION gets a bump.)
