Makefile: allow overriding the llvm-project directory
This allows setting a different directory for experimental changes. For
example, I also have a llvm-project.master directory that tracks the
master branch. It is very useful to be able to temporarily use that
directory:
make llvm-build.master LLVM_BUILDDIR=llvm-build.master LLVM_PROJECT=llvm-project.master
