I assume you did something like:
LEVEL = /usr/software/llvm
If so, you can't do that. :) The LEVEL must be a relative path from the
local directory and it must also be the case that it is a subdirectory
of LLVM tree.
I think what you want is an LLVM makefile project. Please take a look
at the "sample" project (llvm/projects/sample) and also:
http://llvm.org/docs/MakefileGuide.html

Its trying to find the LLVM Makefile.common file but not succeeding
because of the way it uses the LEVEL variable.>

That, however, I would expect to work. Not sure why it doesn't. What
happens if you do this?

Please see the Makefile Guide. You can set your own project up using the
LLVM Makefile system.
