sdl2: fix build with --disable-threads
SDL_LinuxSetThreadPriority() has been added since version 2.0.9 and
https://github.com/SDL-mirror/SDL/commit/
f25a7fa870bdceb339e5105973f689606bcb9086
However, this function is used in src/dynapi/SDL_dynapi_procs.h even
when SDL_THREADS_DISABLED
However, when SDL_THREADS_DISABLED is set, SDL_LinuxSetThreadPriority is
not defined because thread/pthread/SDL_systhread.c is not built
So check SDL_THREADS_DISABLED in addition to __LINUX__
