The attached patch is pretty gross, but at least allows bootxx_ffs
to build.  bootxx_lfs is still too big, so I've disabled the
building of that for now.  I'm not sure if anyone actually uses
bootxx_lfs?  I did test it once ages ago when I was playing around with
boot-off-LFS-on-raidframe.  Note that I haven't tested the resultant
bootxx_ffs yet - my alphas are turned off right now.

Should I commit this so as to at least allow builds to work again?  If
so, I'd also add a doc/HACKS entry too.  I'm also asking the binutils
folks what we can do about this.

Simon.
