Build fix with clang.
When building sdl 1.2.14 with the Clang compiler http://clang.llvm.org .
The build fails in src/video/mmx.h with the following error:
--------------------------------------------------
./src/video/SDL_RLEaccel.c:831:5: error: invalid operand for instruction
CHOOSE_BLIT(RLECLIPBLIT, alpha, fmt);

--------------------------------------------------
According to the clang developers this is a invalid inline assembly.
Using the attached patch from the last commit in the below bug report fixes the
compile.
