sim: aarch64: remove recursive make entirely

In order to compile arch objects from the top-level, we need to
generate the modules.c file, so move that logic up to the top
level first.  The deps are a bit imperfect currently due to the
common/ files not being shared.  That'll improve as we share the
sources more.
