[cfe-dev] Can't build CLang with CLang on FreeBSD

Okay! Get this: it took about a day and a half to complete, but I was
able to compile Clang [Release] using Clang [Debug].  Thus, I've had
to use GCC to build Clang [Debug], and then use Clang [Debug] to build
Clang [Release].   (When I try to build Clang [Release] with GCC, it
creates a b0rken executable.)  Trying to build Clang [Release] with
Clang [Release], however, left me with:
