[ports-gcc] Unbreak games/pingus

> http://build-failures.rhaalovely.net/sparc64/2019-05-03/games/pingus.log
(same thing on macppc)

A header is missing, adding it fixes indeed the issue.

The runtime has been tested successfully on macppc and amd64.

While here, HOMEPAGE has been moved to https.

Comments/feedback are welcome!
