Log:
When not compiling in unit-at-a-time mode (for example when compiling at
-O0), the gcc inliner is still being run.  Make sure it doesn't do anything
by marking all functions uninlineable.  The inlining is being ordered by
cgraph_finalize_function, in this part:
  if (!flag_unit_at_a_time)
    {
      cgraph_analyze_function (node);
      cgraph_decide_inlining_incrementally (node, false);
    }
Since the cgraph logic is a twisty maze of passages, I didn't dare turn this
off, and instead chose the wimpy way out.
