	Subject: [PATCH] Don't allow `DESTDIR` to influence LLVM builds

	When running a command like `DESTDIR=foo x.py install` in a completely
	clean build directory, this will cause LLVM to be installed into
	`DESTDIR`, which then causes the build to fail later when it attempts
	to use those LLVM files.
