annotate src/power/linux/SDL_syspower.c @ 5030:6a0803e47c7b

Greg Jandl to SDL I *think* the patch below works correctly: sdl-config gets the -march flag and SDL builds fine. Perhaps there's a better way to get the -march flag into both CFLAGS and SDL_FLAGS w/o dragging along more cruft, but adding it to BASE_CFLAGS seemed the best bet to my eyes.
