Log Message:
games/xracer: NOT JOBS SAFE

I don't know what changed, but this game starting failing on both
platforms due to build order.  Setting MAKE_JOBS_UNSAFE=no was the
solution.

The homepage is long gone, so that was commented out.

FreeBSD Ports deleted this game in 2011-04-12 (ports/151390)
It has not been developed since 2000 and the game was never finished.
The developer website has disappeared

Pkgsrc should follow suit and also delete this subpar package.
