The level of support for AVR in 3.0.4 was rudimentary, only atmega128 is
supported in the MakeFIle.  The  support for AVR is still improving with
time so use either the development branch, or the latest release version
(if you prefer release versions).  The bootstrap compiler required is
determined by the source version, not the cross target.
