Yeah, I have cherry-picked these two upstream commits before you have
mentionned it...

0001-Mention-symbol-name-in-non-constant-.size-expression.patch
(Cherry-picked from commit b9521fc0be7945fc842ce1197e241a023378125d)
0002-Revert-the-last-change-on-gas-elf-bad-size.err.patch
(Cherry-picked from commit cbd141bb69f791de7ea1581abe7afb34f0c61288)

... and have built with them a new binutils Debian package.

The error looks now like this (sorry for the German output):
...
AS arch/x86/kernel/entry_32.o
/home/sd/src/linux-2.6/linux-2.6.38-rc7/debian/build/source_i386_none/arch/x86/kernel/entry_32.S:

make[6]: *** [arch/x86/kernel/entry_32.o] Fehler 1
make[5]: *** [arch/x86/kernel] Fehler 2

Anyway, before more riddling around it would be very helpful to have a
clear pointer if there is a fix around... That building, testing and
installing took me now several hours.
And... yeah, backports to 2.21-branch appreciated.
