[MPlayer-dev-eng] SSE check leaves a coredump behind

[Steven M. Schultz]

Hi!

	On systems without SSE/SSE2 support the test for those instructions
	leaves a coredump file behind.

	The small patch below catches the SIGILL signal and exits with 
	non-zero status but without creating a core file.

	Cheers,
