Ahh, you're going in the right direction: show what you want to achieve,
not how you think it would be best to do it.

Well, I think the cheapest and least error-prone operation is the
creation of a static library.  Unless you need it otherwise, set
  RANLIB = :

in this, and
  noinst_LIBRARIES = libfoo.a
  libfoo_a_SOURCES = ...

You could even hack like this (but I won't guarantee that it won't break
with another Automake release):
  AR = :

I don't think this is all that ugly.  But I don't see why you should
need BUILT_SOURCES, at least not from this snippet alone; you could just
as well list those .o files as dependencies to all-local, or put them in
some libexecdir_SCRIPTS or so.  And I think you can make use of COMPILE
to your advantage, instead of using CC directly.

Hope that helps.
