Thanks!  This is approved, but please correct this one gotcha:

The text inside @var should not span more than a single token.  Since
in this case `location' is not marked with @var elsewhere, I'd suggest
to rewrite this like so:

  Other BFD files have a built-in location info; they will be
  restored at offset @var{bias} from that location.
