For an example (admittedly not the most elegant, but it works), have a
look at lib/clang/clang.build.mk, which contains the common make-related
bits for clang and llvm.  This is included by the clang and llvm
libraries (which live under lib/clang) via lib/clang/clang.lib.mk, and
by the clang and llvm programs (which live under usr.bin/clang) via
usr.bin/clang/clang.prog.mk.
