I've got a makefile that tries to build llvm and llvm-gcc from source,
and then run the test suite. I've found that I have to

1. build llvm
2. build llvm-gcc (which uses libraries built as part of llvm)
3. as you say, *reconfigure* llvm (without using a config.cache!) now
that there is a working llvm-gcc for it to find

Is this reconfigure step really fundamentally necessary? It's a pain
for me because there's no simple way to represent the fact that that
step has been done as a dependency in my makefile, and because after
the reconfigure "make" thinks that it needs to rebuild llvm.

Thanks,
Jay.
