How was the package suppsed to build itself then, by hand? *g*

I can't get the cross' binutils-sparc (package hacked from binutils-m68k)
to build.
dpkg-gencontrol -Pdebian/tmp/binutils -pbinutils-sparc-linux
dpkg-gencontrol: error: source package has two conflicting values -
binutils-sparc-linux and binutils-m68k-linux
make: *** [binary-arch] Error 29
I edited all the references in debian/* from m68k' to sparc', and I don't
know enough about the package to even guess what else might need to be
tweaked.
