*-native packages can touch things on the system, any other packages
shouldn't and if they were found to be, it would be a bug and should be
fixed.

Its never going to be possible to make make OE build everything it needs
itself since you always need some prerequisites (e.g. a initial
toolchain).

Personally, I use OE/Poky on Ubuntu and Slackware. There are others
using Gentoo and other systems. Ideally it should work on most systems,
you might see problems with -native packages, you shouldn't see problems
with non -native ones.
