bfd cache control

I see no reason why the bfd_cache_close function cannot be used.  By
"export properly" I assume that you mean add a prototype to the
appropriate header ?  I am not sure which header this would be.  It is
already in bfd/libbfd.h.  Where else would you expect to find the
prototype ?
