Ick!  Since we never install convenience libs, wouldn't it be cleaner to add
RANLIB_cmds to libtool?  Where darwin sets it to do nothing on fat convenience
libraries, but run $RANLIB otherwise.  I'm quite happy for RANLIB_cmds to call
a shell function if that helps the implementation, but be careful to only drop
the function in libtool if it is used (i.e. $host_os ~= darwin*).

Happy with this bit though.

Cheers,
        Gary.
