While I agree the PACAKAGE_BUILDING case must produce a genuinly portable
binary. I can not see the point in deliberatly making it difficult to
get equivalent performance to the various Linux distros.
Realisticly most folk tring to run myth are going to have i686 or better with 
MMX.(Having a working via unichrome kernel module may change this)

My incliniation is the port should self tune, unless PACKAGE_BUILDING or
there a optimisation flags from make.conf.
