Fixed. Both the instance you noticed, Uros, but also another
along the i386 mach-o path.

i686-darwin cleanup
This appears as if it might work.
I can't seem to trigger the branch island path here. It looks like
only darwin8 needs this, and even configuring for i686-apple-darwin8
doesn't trigger.

hm. doing a cross to darwin-8 should produce the requirement for stubs and
branch islands (the latter, I think are ppc only).
----
You should also be able to trigger the branch island path by using
-mmacosx-version-min=10.4 on Darwin 9 or 10 (when building for PPC). This
should also also trigger generation of stubs for function calls on m32 x86 and
ppc.
(will try and look later - but tied up with other hassles right now)
