Summary: Investigate on the usage of -DRUNTIME_CPUDETECT

I was pointed at the RUNTIME_CPUDETECT build flag for ffmpeg/gst-ffmpeg. This
flag seems to postpone the choice of per-CPU optimized functions until runtime.
This would especially help to run binaries built on Altivec capable machines on
non-Altivec machines, eg. G3 CPUs.
This flag should be promoted to a configure flag in gst-ffmpeg, and should be
set by default -- if it holds its promises.
