avr: pass the correct -mmcu flag to the linker

Browse Source 
It does not appear to be necessary for these devices but might result in
more appropriate libraries to be linked in.

It is best to _not_ specify the exact MCU because otherwise a few other
settings (such as startfiles and some linker script configs) also get
set, which we do manually anyway and should not be interfered with.

I discovered this while working on support for the atmega1284.
