[FFmpeg-user] --enable-runtime-cpudetection needed for distributable?

Hello all.
I'm familiar with the fact that using
results in a distributable that "might only run on the machine it was
compiled on."
Is the same try for ffmpeg if I leave out the
configure flag?
What cpu does it use if I leave out that flag? The host cpu?
also what is the relationship between --cpu= and --arch= and
--enable-runtime-cpudetect, anybody know?  Do they just map to gcc's
-mtune and -march?
Thanks for any help here.
