Subject: SDL_stretch crash on OpenBSD

Hello,

I noticed that on OpenBSD, SDL programs crash on some asm in
SDL_stretch.c. The workaround is to #undef USE_ASM_STRETCH.  The
OpenBSD SDL port maintainer suggested that I let you know about
it.

This is reproduced by hitting the 'f' key for fullscreen mode in
ffplay, the ffmpeg media player.

Thanks,
Deanna

I think we can use mprotect() to make the stack executable.
