[MPlayer-dev-eng] [PATCH] _altivec forced to no during check for altivec.h

[Steven M. Schultz]

 	The _altivec variable is clobbered (forced to 'no') during the
 	check for <altivec.h>.   This causes G4 based systems which do
 	have Altivec instructions (but lack altivec.h - OS/X systems for
 	example) to not use them
 
 	Defining another flag "have_altivec_h" would seem to be a solution
	to the problem.   The small patch is attached.   If there is a
	better way to handle PPC machines without altivec.h (OS/X is
	one such system) that's fine too ;)

	Cheers,
	Steven Schultz
