Sounds a bit more insane to what I am doing currently...

The more I think of this, I start hoping that recipe specific sysroot
plus sources (of all dependencies) should be enough for remote
debugging. In case this is true: Would it be a big deal to extend
recipe specific sysroot by source files? For performance reasons
populating source files should only be an option set in local.conf.
