Hi Daniel,

*sigh* Yes you are right. What do you think of the following patch ?
It works for me, but my makefile-fu is not the greatest so there might
be a better way of expressing what we want.
This patch is for the binutils subdirectory. I have a similar patch for
the ld subdirectory and a simpler one for the gas subdirectory as that
only has one generated source file. If there are no objections to this
method then I will apply the patches tomorrow.
Cheers
Nick
