This commit introduces the build infrastructure changes needed for creating a shared RO library. (libsharedobjs). The end goal is for the library to contain various objects that can be shared with both the RO and RW EC images. Now, there are 3 make goals: ro, rw, and libsharedobjs. In order for changes that are only specific to a single image (ie: RW only) to be applied correctly, the object files are now built separately for the RO, RW, shared objects library targets. NOTE: Certain EC targets are incompatible with this model due to the fact that only one image is present within flash at a time. BRANCH=none BUG=None TEST=make -j buildall tests TEST=make -j BOARD=cr50 xrefs TEST=make BOARD=samus dis TEST=Built samus EC image and compared that the final EC image was identical to the upstream version (except for the git SHAs & version strings).
