AdaCore's AVR compiler comes with a sample application somewhere (I
don't remember where).

When using gcc for AVR you have to specify the target MCU at the
compile and link steps with the option -mmcu=<name of mcu>. In your
example you missed that option in the compile step.

AVR-Ada /= AdaCore's AVR compiler.

AVR-Ada V1.1 still uses gcc-4.3.x, AdaCore's AVR compiler is based on
gcc-4.5. That version has a serious problem if you use locally renamed
variables of the MCU's registers.  Either use AVR-Ada V1.1 or wait a
few days/weeks for AVR-Ada V1.2 which will use gcc-4.7
