Enable building clang separately from llvm

Note that there is some duplication when building clang now. The llvm source
is unpacked twice, ./configure is run twice, and two small unit test
libraries are compiled twice. IMO this is a fair tradeoff for having
llvm be a separate build unaffected by changes to clang
