Some sparc users have a slightly older version of gcc, built shortly
before 'weak' support was added, which required those symbols to be
defined. Dave Miller thought the compiler problem was widespread
enough to justify changing the source to suit the compiler instead of
forcing sparc users to upgrade. I suspect that super-h has the same
problem of old compilers, I noticed that somebody added the symbols to
sh/vmlinux.lds.
