bfd_cache_lookup

DESCRIPTION
Check to see if the required BFD is the same as the last one
looked up. If so, then it can use the stream in the BFD with
impunity, since it can't have changed since the last lookup;
otherwise, it has to perform the complicated lookup function.

quick answer. Find a file descriptor for @var{abfd}. If
necessary, it open it. If there are already more than
<<BFD_CACHE_MAX_OPEN>> files open, it tries to close one first, to
- avoid running out of file descriptors.
