[Bug c/45261] New: Doesn't indicate failure status when it doesn't support (attiny2313A)

[rootolini at gmail dot com]

When configuration script of avr-libc tries to check if gcc has support for
Attiny2313A it doesn't indicate any failure even if it really doesn't support
it. I found about that trying to build avr toolchain using this version of gcc.

Here is a part of config.log:

configure:5374: checking if avr-gcc has support for attiny2313a
configure:5390: avr-gcc -c -mmcu=attiny2313a  conftest.c >&5
unknown MCU 'attiny2313a' specified 
...
configure:5397: $? = 0
configure:5416: result: yes (which should indicate NO)

this bug doesn't allow to build avr-libc-1.7.0 because it doesn't let 'make' to
build the code.
