Since the geolocation and music-control changes we need eldbus-codegen to
generate some files. Not all setups have this in their normal $PATH so let
allow these setups to set the correct path during configure. This allows our
Jenkins setup as well as others to work again.
this is the correct way to write a build system. one toplevel Makefile.am with the rest of the directories having include Makefile.mk files.
