- use PERMIT_PACKAGE, maintain the information about patents in a
comment but we don't care about PERMIT_*_CDROM any more. additionally
opencv2 is not a multipackages port so -docs doesn't make sense anyway.
- remove base-gcc from COMPILER, base-gcc won't be used on a port
with ONLY_FOR_ARCHS set to ${GCC4_ARCHS} ${CLANG_ARCHS}
- remove ONLY_FOR_ARCHS, it's unnecessary now that base-gcc is
removed from COMPILER :)
- sync WANTLIB, bump REVISION
