I was installing gqmpeg, but mpg123 wouldn't build on a Linux system. So
instead of troubleshooting, I installed mpg321 because "mpg321 can be used
as a drop-in replacement for mpg123."

mpg321 has:
CONFIGURE_ARGS+=        --disable-mpg123-symlink

I was wondering if we could have some bsd.pkg.defaults.mk variable to
select which mpg123 to use so other packages that depend on it can use.

My workaround for gqmpeg was to manually change the DEPENDS from mpg123 to
mpg321.

Any thoughts?
