Upgrade build system #193

Closed wavexx closed 2 years ago

wavexx commented 2 years ago

Replaces #192 => using gcc 7.3 from Microchip
Uses the same ninja/cmake versions as the Buddy FW to reduce duplication
Defaults the toolchain to AvrGcc (using gcc from the dependency tree)
Allows to use the system gcc with AnyAvrGcc as intended
Changes gcc-avr to avr-gcc for consistency

MMU-10 MMU-171

@3d-gussner @wavexx actually I had to include the empty implementation of the __cxx_pure_virtual() even for gcc 7.3 for unknown reason. That's why I put that into PR#192.

In our case I'd personally drop support for avr-gcc 5.4.

I dropped commit 7bb36b5.

Buuuut it didn't have issues with 7.3 (with neither from gcc 7.3 from arduino 1.18 or microchip's. To me it's a canary that the compiler is messing, which is why I would have dropped it.

And now that we will switch to 7.3 also for the MK3, I see no reason to support 5.4 which we know is just full of bugs.
