We use native compiles (in chroots) for our official builds, but do use
cross compiler in chroot to speed up debugging and such.
Of course far from everything can be cross compiled easily, but things
like the kernel is quite easy to do and one of the otherwise pretty time
consuming things to build.
Current build machine we use is an arndale octa (which gives you four
Cortex-A15 cores at 1.8GHz and 2GB ram for about $200). A SATA SSD is
attached via a USB3 adapter for swap space.

Followed the instructions in README.Cross in the gcc-4.7 source package as
well as the binutils package, and use dpkg-cross for any needed packages.
Should be simpler in jessie since I believe it now supports building gcc
for cross compiling that works with multiarch installed packages which
gets rid of dpkg-cross and makes dependancies much nicer to deal with.
