FreeBSD/ports c6f6513 (r424560)audio/codec2 Makefile, emulators/i386-wine-staging Makefile

OPTIONS_SET/OPTIONS_UNSET are global variables, they cannot be used in ports Makefiles.

So, replace them with OPTIONS_SLAVE, OPTIONS_EXCLUDE, OPTIONS_DEFAULT,
where appropriate.

The ghostscript ports are doing something nasty that is certainly wrong,
but I don't want to try to understand it.
