Nice idea, but...

I think that one thing that people often forget about when talking about 
using external compiler to build base system is that FreeBSD is not only 
self-hosted, but also that it supports cross-builds of any of the 
supported arches. This feature would be physically impossible to 
maintain for any extended period of time with 10 supported compilers 
maintained outside of the tree.
