DESCRIPTION
Return a pointer to the transfer vector for the object target
- named @var{target_name}. If @var{target_name} is <<NULL>>, choose the
- one in the environment variable <<GNUTARGET>>; if that is null or not
- defined, then choose the first entry in the target list.
- Passing in the string "default" or setting the environment
- variable to "default" will cause the first entry in the target
- list to be returned, and "target_defaulted" will be set in the
- BFD. This causes <<bfd_check_format>> to loop over all the
- targets to find the one that matches the file being read.
