Well, GCC supports AVR because people wrote AVR support into GCC. ;)
AVR is a bit more "compiler friendly" than, say, the Z80.

AVR is AVR, architecturally speaking.

Well, GCC "supports MSP430" meaning TI distributes a hacked-up GCC
that targets it, yes. That support has not yet (the last time I
checked) been merged into the official sources, which means I'll have
one different, weirdly-configured GCC installation alongside my
half-dozen nice consistent standard ones. No thanks.
