It is still there, I just built a fresh cross-gcc with bintuils 2.1.17,
gcc-4.1.1, and, after applying one patch, the build fails with getuser
problems. Can we have a patch for the CVS, please?

This patch fixes the first build problem:

  LD      .tmp_vmlinux1
arch/m68k/mm/built-in.o: In function `paging_init':
: undefined reference to `__stop_fixup'
arch/m68k/mm/built-in.o: In function `paging_init':
: undefined reference to `__start_fixup'

I don't know if asm/module.h should be included somewhere else, but this
fixes it for me.
