[Buildroot] [PATCH 2/2] package/sdl_mixer: fix static build with tremor

[Fabrice Fontaine]

Static build with tremor raises a build failure since bump to latest git
tree in commit c8e27f3baa90351a417ff6e172d214c4a72e7314. However, it
should be noted that before this bump, tremor was always disabled in
static builds because vorbisidec detection was broken until
https://github.com/libsdl-org/SDL_mixer/commit/565a9a27cc8c184ad0203f004b834880ffd45d32
