I just jumped on binutils-2_21-branch GIT and looked what changed in
gas/ directory.
So there were two patches to consider in the time 2011-03-02 and
2011-02-16 (chronological order, latest listed as first):
[1] commit a57ef8e7f3b214e0cf9ee33bb17c11f9f63bf6aa
"* symbols.c (report_op_error): Remove unnecessary forward declaration."
[2] commit 345bbf7731af2912390e72b86807eb1b2af3e27b
"PR gas/12519"
Reverting [1] still breaks build.
With reverting [1] and [2] I had success.
(Unfortunately, both patches have made changes to gas/ChangeLog, so
for isolating only [2] I had no fun and time).
As a conclusion:
It looks like the "PR gas/12519" patch breaks the linux-next kernel
(or l-n needs some modifications?).
It's up to the experts.
Hope this helps to fix the problem.

P.S.: I have added both revert-patches.

Just FYI (for the "dropped" MLs while finding the "brain bug"):
Finally, with the help of x86 folks and H.J. Lu a fix for the
linux-kernel can now be found in [1].
Commits [2] and [3] from binutils master GIT helped to dig deeper into
the right places.
So I would appreciated both to be backported to binutils-2_21-branch GIT.
@Matthias:
If you like you can use the two backported patches (see file
attachments) for a next binutils upload to Debian/sid.
As usually (and you demanded once from me) I dropped any ChangeLog
entries from the code, but kept the history in the commit-text. Also,
I documented my changes.
So the patches should cleanly apply.
Thanks.
