Toolchain stratum
Stage 1: build a minimal cross compiler with the host's tools.
Starting with a cross compiler ensures that (a) nothing from the host
can leak into the build-essential artifacts, and (b) cross-compiling
build-essential is fully tested and supported, since we always use the
cross code paths.
Stage 2: cross-build the whole of build-essential, using the host's tools
but the cross-compiler toolchain.
Stage 2 GCC outputs code for the same 'bootstrap' machine as stage 1 GCC,
but because stage 2 GCC is also built to *run* on the bootstrap machine
it can only execute inside the stage 3 chroot (due to being built against
a libc with a non-standard prefix).
Stage 3: build the whole of build-essential again, this time using a
staging area containing only the output of stage 2. The result of this
build is fully reproducible.
We do a switch-a-roo between stage 2 and 3: stages 2 chunks are all built
to run on a host *-bootstrap-* while stage 3 chunks are native-built for
a *-baserock-* machine. This works, because the cross build was all for
show (and cleanliness) and the binaries actually still run on the host.
After build-essential is built we do another trick. See
stage2-fhs-dirs.morph for details. Basically, /bin is a symlink to
/tools/bin during stage 2 but in stage 3 it becomes a real directory
again.
