The files generated by the CMake build are completely relocatable
because they compute everything relative to the LLVMConfig.cmake
file location.  The Autoconf/Makefile build system would have to
be taught to do the same thing in the files it generates.  Take a
look at the CMake-generated files to see how they achieve it.
