Well, I'd like to be able to build it from non-freebsd environment.
Eg, eventually from the macosx shipped clang/llvm, or various other
external toolchains. Doubly so for whatever commercial / internal /
bring-up compilers that are used during platform bringup.

The hurt is that our Makefile stuff is still a bit messy. On the plus
side, Brian, Warner in particular have done a great job undoing all of
that and making things cleaner, so big props to them!
