onClick on checkbox would get triggered before actually ticking the
checkbox, which is not the expected behaviour (apparently). This change
makes sure that we call the onClick event handler only after actually
doing our work with the checkbox/select widget (for the other widgets,
things should stay the same).
Convert remaining conditional file building to use
OBJS-$(CONFIG_FOO) += foo.o
one problem with reverse meaining (in util/) fixed with local 'hack'.
Cleanup and remove stuff which is now default targets.
Ditch the building of an archive (.a) in favour of linking all objects in a
directory into a lib.o file. This makes it easy to link in subdirectories
and more importantly keeps the build logic in the local subdirectories.
Note: after updating you will have to rm **/*.a if you do not make clean
before updating.
