I know, but maybe they should move towards using pkg-config?
It's just installing 1 extra file for each arch to /usr/lib$n/pkgconfig/llvm.pc

A dummy llvm.pc would look like this:

prefix=/usr
exec_prefix=/usr
libdir=/usr/lib
includedir=/usr/include

Name: llvm
Description: Low level virtual machine
Version: 2.8
Requires: libffi
Libs: -L${libdir}/llvm -lLLVM.* -lpthread -ldl -lm
Libs.private:
Cflags: -I${libdir} -fexceptions -D__STDC_LIMIT_MACROS

This would also work better for multiarch systems like debian.
