The common pattern I see in all the failures below is that hhi8(operand) is
present at the faulty line. Looking at the CVS logs and diffs for binutils
(gas/config/tc-avr.c), it looks like it was broken between May 16 and
Jun 11 (hhi8 was removed and added back). I'm guessing your binutils source 
was checked out between those dates.

I tried building the latest released 2.2 snapshot
(http://ftp.gnu.org/gnu/binutils/binutils-2.22.tar.gz), and it built
avr-libc just fine. Just to make sure broken binutils is the problem, can you 
do that and see if that fixes the problem?  

If that works, then you can always update the version you checked out
from CVS and build it again - the latest tc-avr.c contains hhi8 and
should work.
