That's possible, but I don't believe so.  I understand that "make binutils" 
will compile the target binutils.  But when I just run "make" it successfully 
builds the host binutils, then continues on to build the target binutils, 
where it fails.  So I was just running "make binutils" as a quick way of 
recompiling the target binutils while I was trying to figure out a way around 
the problem.  I now realise that the problem is this package (target binutils) 
shouldn't be being built at all, so you can probably forget my comment about 
"make binutils" now :-)

No I don't want the target binutils, but I don't seem to be able to disable 
it.  It's deselected in the buildroot config, but it still seems to be getting 
compiled.  How would I go about working out why?  I'm not sure how to debug 
all the make dependencies.
