not sure if it's a 'laziness' thing - the flag was added in a quite definite
manner (it's just not clear as to what problem it was resolving).

==

it's also not clear if Apple acknowledge that it's a bug and it was 'fixed' at
least on Darwin 9/ld85 (and then 'unfixed' on darwin >= 10) - or whether
there's some other reason that it doesn't manifest on darwin9.

anyway - you could try editing gcc/configure and setting ranlib_flags = "" on
Darwin11 and reg-test.

if that is a solution to the problem, and no-one can come up with any reason
why we should include common symbols in the table of contents for darwin
archives, then maybe we should just do this for darwin >= 9.
