There is a rudimentary avr-gcc build.

I am thinking about creating of native and Canadian cross recipes for
avr utilities to be able to compile and upload Arduino sources from my
Zaurus.

Support for shared libraries, OS, command line and package management is
far above capabilities of these devices. But I can imagine recipes for
static libraries (e. g. avr-libc; however most standard libraries would
be too heavy for AVR) and just one application package that will become
an "image" (= firmware), linking against these static libraries. Maybe
OE is an overkill for this task. Make could do the same with a smaller
complexity, but on the other hand, at least avr-libc (and the Arduino
library) has to be build in this way.

And finally, it might be interesting to invent a way, how to convert
linux kernel drivers to microcontroller drivers and vice versa. I have
been just thinking about porting of drivers/w1.
