I merged this however I notice there are "yet more" floating
dependencies since sdl is floating (at least).

For sdl, can we add the PACKAGECONFIG option however also add an entry
to local.conf.sample which documents how to enable sdl for qemu-native?
I suspect that is the option most people are using to make runqemu
useful. We may also want to have the option of assuming libsdl-native is
provided since otherwise we end up in the tangled world of GL support
and we don't want to build our own libsdl-native in most cases.

Cheers,

Richard
