Because you have vast experience to the contrary?  Look, even x86_64 is 
topping out on speed and moving to a more-core and more-systems-per-rack 
model.  Cross compilation solves yesterday's problem, not tomorrow's. 
If build speed truly is a fundamental issue to becoming PA the answer is 
to harness multiple systems for a single build, not to use a somewhat 
faster system to make up for the speed of a somewhat slower system. 
Scaling across more cores than fit in a single SMP Linux environment is 
the only sensible approach to future build speedups.  Though is an 
interesting challenge, it is completely beyond the scope of primary 
architecture requirements.  Please, let's drop talk of cross compilation.
