So does this mean we can count you in? (I think we can, but you never
explicitly said yes).

The avr is a 8 bit OS less mcu, the avr-gcc chain generates code to run
directly on the bare hardware. There is no "executuble" format, no OS,
no nothing. Also notice that every makefile for AVR software under the
sun (that I know of) refers to avr-gcc as avr-gcc and nothing else.

Thus for exact the same reasons why we want
/usr/<target>/{bin,lib,include} and not seperate <target> dirs under bin
lib include, we want avr-gcc to be just plain avr-gcc. The only
alternative I can come up with would be avr-nothing-gcc or avr-NA-gcc,
which both are bogus.
