Yes, building from zero is the only way of being sure of what is
happening. As soon as *any* system-wide change, such as a toolchain
configuration change, is made, then a rebuild from zero is needed.

Partial rebuilds, as documented in the documentation, are possible on a
per-package basis, when you fully understand what you're doing and how
Buildroot uses the stamp files. You can very easily break things, or on
the opposite, get something working that wouldn't work with a build
starting from zero.

When doing work on packages, I do use partial rebuilds a lot, but I
also make sure to do a full rebuild at the end to make sure everything
is in order.
