The problem with using a BFD'd crunchide is that we'd need to make sure
that the licencing on the current version is compatible with the GPL.
BFD is GPL'd and not LGPL'd, meaning anything that is linked against
libbfd must also be GPL'd (or have equivalent licencing terms).

In the case of mdsetimage, the author allowed a change to the file's
licencing conditions so that it was compatible with the GPL.  The
licence on crunchide isn't standard BSD - if you know that it is
compatible with the GPL then using BFD is another option.

Technically, I'm not sure whether or not I perfer my patches to the BFD
version.  The external calls to grep and egrep in my patches are a bit
