Right.  GDB gained the function first, and the bfd one was
added afterwards:

http://sourceware.org/ml/binutils/2003-01/msg00511.html

"It has become clear recently that GDB is not the only program which
would benefit from these separate packages; notably objdump and the
oprofile post-processing tools require access to them. Rather than
duplicate the same section-extracting, path-searching and
checksum-matching code in these tools, it was suggested that we
centralize the feature in binutils itself. "

So your patch has been the intention all along.

Looks good to me...
