For building packages I use pbuilder and for other platforms are combined 
using qemu-user-static == base image is created using qemu-debootstrap. 

It's great, because it can run building on tmpfs, is not limited by the size 
of memory and can fully use parallel build (DEB_PARALLEL_JOBS). This would 
not be possible with full virtualization. With that builds runs acceptably 
fast. And one builder builds for any of the platforms (now amd64, i386, 
armhf, armel, mips, powerpc) - platform is determined by BASETGZ.

On powerpc was a problem with CMake, which crashed immediately after start. It 
helped when I replace qemu-ppc-static binary in the base image by the same 
binary from 32 bit qemu-user-static package.
