By setting PKG_OPTIONS.pkg, you do not *replace* the default options for pkg,
but you *add* to them.  So setting PKG_OPTIONS.SDL to "aalib arts esound" when
the default is "aalib arts esound nas" doesn't change anything.  You have to
explicitly disable nas by adding "-nas", because that's what you want.

If you want to ignore the default and set every option explicitly, start with
"-*", e.g.  "-* aalib arts esound".
