I don't know the original intention of the .IGNORE, so I just assume, that
it's there because some of the targets abuse the image generation code for
stuff like DTBs or other artifacts.
So I'm not sure, whether this misuse means broken only source file/dir or it
might mean problem with the destination file/dir as well.
This would probably need more checks (and testing) so it might be probably
better to bite the bullet and fix the targets causing the problems and fix
them, then removing the .IGNORE altogether without any other additional
