[PATCH 1/3] sim: build: hoist lists of common objects up

[Mike Frysinger <vapier@gentoo.org>]

In order to create libsim.a in the common dir, we need the list of
objects for each target.  To avoid duplicating the list with the
recursive make in each port, pass it down as a variable.  This is
a temporary hack until the top-level creates libsim.a for ports.
