Details:

I just pulled the avr-libc trunk and got this compilation error:

avr-gcc -DHAVE_CONFIG_H -I. -I../../..  -I../../../common -I../../../include
-I../../../include  -I../../../common -I../../../include -I../../../include -x

System configured like so:
./bootstrap
./configure --build=`./config.guess` --host=avr make On Ubuntu 12.04 with
avr-gcc (GCC) 4.5.3.

After poking around the email archive, it looks like there have been other
issues like this and the result was to not compile those libraries with
protection like so: 
#if !defined(__AVR_TINY__)

I looked into utoa_ncheck.S and found that it had this: 
#if !defined(__AVR_TINY).  
Is it possible that the protection variable changed names at some point?  I
found several other files that had this (presumably) improper protection
variable:

./libc/misc/utoa_ncheck.S
./libc/misc/ultoa.S
./libc/misc/ultoa_ncheck.S
./libc/misc/itoa.S
./libc/misc/ltoa_ncheck.S
./libc/misc/ltoa.S
./libc/misc/utoa.S
./libc/misc/itoa_ncheck.S

I fixed them and provided it in the attached patch.

NOTE: patch is untested other than compiling entire library.  I don't have a
avrtiny to test with.
