No, but its pretty straightforward, just do another configure and make
of llvm using the built llvm-gcc, then another llvm-gcc with the
second llvm and using the first llvm-gcc.

And yes, you can see what it is doing by checking the first two lines
of the logs, the first line is the command that is run, the second is
the directory it ran it in.
