[BUG] Linux-2.4.12 does not build (Sparc-64 & DRM)

[Leif Sawyer]

Just a quick bug report -- I haven't had time
to track this one down yet.

Enabling DRM/DRI support on a Sparc64 kernel
with Creator/Creator3D graphics does not build
correctly:

ld -m elf64_sparc -T arch/sparc64/vmlinux.lds arch/sparc64/kernel/head.o

This makes correctly on 2.4.10 and earlier.
