[big-endian] unbreak games/mvdsv

About mvdsv, the QuakeWorld server,

I don't play this game, but I want to fix an error in CMakeLists.txt,
which broke this package on big-endian platforms. kmos had added
BROKEN-sparc64, but I got the same error on powerpc. This diff adds
the missing PRIVATE keyword, so I can package mvdsv on powerpc.

I didn't bump REVISION.
ok to commit?
