When building EC image, in the majority of cases the RW and RO images
are built from exactly the same set of object files, and the RO set of
objects is used as a template to derive the RW set of objects.
This is not necessarily correct in all cases, let's just create an
abstract set of object files and use it to derive the sets for RO, RW
and sharedlib as appropriate.
BRANCH=None
BUG=chrome-os-partner:43025
TEST=tested as follows:
- changed the Makefile to sort all object files in a single list
(instead of sorting them by directory, with the directory list
unchanged). Built all targets, saved all .smap files. Then applied
this change and again built all targets. Compare all smap files,
there were no differences.
- modified board/samus/board.h to trigger building sharedlib
objects, verified that build/samus/sharedlib built fine.
