They aren't ports, they are the values of the CCVER environment variable
that seamlessly switches between the base compilers.

The value is static.  Even if the base compiler is upgraded to 5.1 or
5.2, it will be still be known as gcc50.

The "gcc5" value of CCVER forces selection of the port compiler lang/gcc5.

The gcc version scheme change was pretty pointless (it could have easily
been 5.0.1, 5.0.2, 5.0.3, 6.0.0, 6.0.1, 6.0.2) but that's a different
discussion.  The fallout from the version change has been continuous
though.  It even broke lang/gprbuild, and caused quite a mess with
dports modes to bsd.gcc.mk as 5 < 47.  Just a bad idea.
