Confirmed. Something about this procedure with 2.6.8-rc4 is hosing
/dev/null, and I have to delete it and mknod again. Is this a known
bug, or have I discovered something that everybody's known about
forever, and I should slink away. Or maybe I don't understand how to
build/install 2.6 correctly?

for starters:

useradd -m jeglin
su - jeglin
tar xfj linux-2.6.8.1.tar.bz2
cd linux-2.6.8.1
make menuconfig
make all
cd ~jeglin/linux-2.6.8.1
make modules_install

sudo make modules_install

reboot

the binutils check (?) will remove /dev/null

Yep - Tom Rini already notified me about this issue.
Problem is the way as handle output files.

Now I wonder why I do not see the problem here when executing the
culprint part of arch/ppc/Makefile manually:

sam@mars kbuild $ sudo ls -l /dev/null
crw-rw-rw-  1 root root 1, 3 Jun 15 23:54 /dev/null
sam@mars kbuild $ sudo echo dssall | as -many -o /dev/null >/dev/null 2>&1
sam@mars kbuild $ sudo ls -l /dev/null
crw-rw-rw-  1 root root 1, 3 Jun 15 23:54 /dev/null

Tom asked if we could use mktemp in the build process,
but I really do not know enough about potential security issues
to start doing this.
With mktemp we could avoid using /dev/null in the as check.

Another possibility was to parse the output of:
as --version | head -n 1 | cut -d ' ' -f 3
And then some sed/awk magic to fetch the three first numbers and
always make then two digits wide: 2.14.90.0.8 => 021490
