So this was a build from scratch and I didn't override any defaults
concerning LLVM (my main thing is -DPORT=Nix) A week ago before the B3
drop (llvmForJSC), it built and there was no complaint about this

I didn't do anything to my installation. But I think I may see the
problem. On my distro, I have the directories,

I do not have anything without a version number. So
'llvm-c/Analysis.h' is not going to find anything.

I suspect the correct solution is to #include "Analysis.h" and
INCLUDE_DIRECTORIES should specify the correct llvm include directory
based on the correct find_* logic.
