From mk/

Just add a PKG_OPTIONS_LEGACY_VARS line to the file.
It's also possible to add negated options this way, i.e.

I don't think you should change the default options. People
who don't want them have already adjusted...

PKG_DEFAULT_OPTIONS is user-setable and should _not_ be used
in files. The variable you want to use instead is
PKG_SUGGESTED_OPTIONS (see mk/ and the guide).

The option names for at least runtime-cpudetection, win32, xvid,
and real should be prefixed with "mplayer-" because I don't think
other packages will use them.

Option descriptions for all options (including the package-specific
ones) should be added to mk/defaults/option.descriptions.

Why is arts disabled on SunOS (I know, not your change)?
