Yeah I manually changed the x86_64 file to -march=x86-64 and it works fine

As far as the ISO's are concerned I used your x86_64 test3 iso to install... 
after a bunch of fiddleing I have a pure 64 bit system... no multilib... and
I'm building up a personal grimoire that has fixes for spells to use 
x86_64-unknown-linux-gnu for the host (several don't seem to see it as valid)

As for the specfiles yes to be more specific you need three even though there
isn't going to be any difference between the generic x86-64 and intel em64t
other than the filename... I checked gcc 4.1 and they haven't gotten in there
either so I don't expect gcc to have that arch spec for a while...
