[PATCH] make ar faster

Hi Oleg,

Thanks for creating this patch.  I have gone ahead and applied it.
I considered changing the patch so that the buffer size was dynamic,
using a smaller buffer if the reduce_memory_overheads flag was set
in the bfd_link_info structure.  But I did not find an easy way to
get hold of that structure.

Cheers
