Add multi images support
This adds the make infrastructure to build multiple SoC or board specific images from a single barebox binary. The basic idea is that we no longer have a single pbl, but instead multiple pbls, one per image if necessary. Each pbl is defined by its entry function so that each pbl can do exactly what a given board needs. Additionally the pbls together with a self extracting barebox binary can be encapsulated in specific image formats. squashed in build fixes from Lucas Stach for make version >= 3.82: Split Multimage Makefile rule in explicit and implicit parts Fixes build with make version >=3.82 Frome the make 3.82 NEWS file: * WARNING: Backward-incompatibility! In previous versions of make it was acceptable to list one or more explicit targets followed by one or more pattern targets in the same rule and it worked "as expected". However, this was not documented as acceptable and if you listed any explicit targets AFTER the pattern targets, the entire rule would be mis-parsed. This release removes this ability completely: make will generate an error message if you mix explicit and pattern targets in the same rule.
