[PATCH 1/2] build: Move variable definitions to Makefile.global

[David Bremner <david@tethera.net>]

I noticed when trying to use VERSION (and derived variables) in a
subdirectory that the top level Makefile.local needed to be included
first. But according to c10085c77b407d9ea704f8b4f9e0a805f63e72cb it
actually needs to be last. To break this conflict, move the variables
definitions into a new Makefile.global.
