GCC 6 has branched for the release of GCC 6.1 and GCC trunk has become

the home of development for the GCC 7 series, so track this with a new
gcc7-devel port, starting with the 20160417 snapshot of GCC 7.0.0.

For the coming months, this will be highly volatile and likely broken
in various ways at various points in time, so not recommended for any
production use.
