I didn't mean a different compiler, just not a full "toolchain".

As far as my knowledge of Linaro's process goes, stage 1 uses the
system libraries and tools (could be cross), and they use the stage 1
to build the intended versions of the libraries and tools (stage
1.5?), and use that "incomplete" build + new libraries and tools to
build stage 2. Stage 3 should be identical, for verification
processes.

The difference with LLVM is that we don't build the libraries with
stage 1's Clang, but the system compiler/tools/libraries as well,
making it a simple 2-stage build, as opposed to a 2.5 stage build.
When it comes to the C libraries, we don't even build them at all, and
use the system libraries even on stage 2.
