When building the latest 2.4.0-010109 kernel with DRI support enabled,
I got the following link-time error:

     ld: drivers/char/drm/drm.o: linking 64-bit files with 32-bit
     files
     ld: drivers/char/drm/drm.o: linking constant-gp files with
     non-constant-gp files

It turns out that drm.o was built as follows:

     rm -f drmlib.a
     ar  rcs drmlib.a init.o memory.o proc.o auth.o context.o
     drawable.o bufs.o lists.o lock.o ioctl.o fops.o vm.o dma.o
     ctxbitmap.o
     rm -f drm.o
     ld  -r -o drm.o drmlib.a

Looks like the ar output confuses the linker.  I don't even know if this
is supposed to work with the current toolchain.  In any case, if you
remove the ar step and use ld -r directly the problem disappears.  The
enclosed patch fixes the DRI Makefile to remove the ar step.
