I have one of the new Pi's with 1GB ram. With a fast 64GB microsd card ($21 on black friday). I've been pretty impressed with fast it compiles with make -j4.

Heh? Debian cross toolchains work fine: https://packages.debian.org/sid/gcc-4.9-arm-linux-gnueabi for armel and https://packages.debian.org/sid/gcc-4.9-arm-linux-gnueabihf for armhf

I'd recommend just using a project like buildroot - it's really easy to begin with, and afterwards every odd device you eventually decide you need to cross compile for (old router with a MIPS CPU, etc.) becomes just as easy.

I went one step further and built a Canadian that was built on x64, ran on raspberry pi, and targeted teensy cortex m4!

Great, this brings me one step closer to a dream: setting up distcc on every computer in the house so I can build rPi software in seconds, not hours..

Cool if you're running Debian.

Well, not having to build your own cross-compilers is a HUGE reason to run Debian. Other distros probably have packages too in any case.

Those packages haven't been in Debian for that long but I'm sure as hell glad they are.

Cross compilers are still really difficult.
