Vorbis playback broken on Wii U (possibly other platforms?)

[vaguerant]

On at least the Wii U, attempting to play Sega CD/Mega-CD audio encoded as Vorbis entirely crashes the console, requiring a hard power off. Eke-Eke suggested that the Wii U version may not be compiled with either libvorbis or libtremor, one of which is required. Identical files play normally on the standalone (non-Libretro) Wii build of Genesis Plus GX, so the cue file and oggs are not at fault.
