Hmmm, OK, but I still don't see what that part of the patch has to do
with the rest of the patch.  What sets c_flags-$@?

+c_flags-$(base)$(objext) := $(c_flags)

That part of the patch is okay. The libgcc makefile is much more imperative than your usual makefile, so using := is the right thing to do.
