Subject: Force configuration of some projects before others.  In particular,
 some projects rely upon llvm-gcc, the LLVM test suite, and poolalloc.  This
 ensures that the aforementioned projects have their object trees created
 first so that other projects can find their object trees when they themselves
 are configured.
