thanks for the explanation, but I still don't understand why
it is done this way. Why not just get Apple people to run some
script, rather than trying to have "make" automagically do an

Newcomers to llvm-gcc regularly try to build with srcdir == objdir.
Some of them come on irc and ask about why it fails, but probably
