Testbuild not working

ioquake3.x86_64: symbol lookup error:
ioquake3.x86_64: undefined symbol: SDL_DequeueAudio

running chakra linux,without test build it was working

ioquake3 test builds now require SDL 2.0.5 or newer. You can also compile ioq3 yourself to use an older SDL 2 version that is included in your distro.
