I'm confused.  The old rules are for $(lpfx)whatever.o and the generated
rules for the objects with matching sources are for lib_a-whatever.o, but
the list of objects doesn't use "lib_a-", which I suppose means that they
are built using default rules instead of the ones in the Makefile.  Should
the list in extra_objs use a prefix so they are built using the specific
rules?
