[avr-libc-dev] build break regarding avrtiny10

[Axelrod, Ben]

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.

Thanks,
Ben
