One other alternative to the patch proposed earlier.  The reported bug happens
only when optimization is turned on as the early inliner pass invokes
incremental inlining which calls optimize_inline_calls and triggers the above
failure.  So, the fix is then as simple as:

Index: tree-inline.c

          && !cg_edge->callee->local.redefined_extern_inline
+         /* During early inline pass, report only when optimization is

          && (reason != CIF_BODY_NOT_AVAILABLE || !flag_generate_lto))
        {

Seems like the right fix to me. Ok?
