Currently, we rely on an existing external cross-compiler targetting
the target, to build the C library.
This can pause quite a few problems if that compiler is different from
the one we are building, because it could introduce some ABI issues.
This patch removes this dependency, by building the core compilers
as we do for standard cross, and also by building the binutils and
gcc, for running on the build machine.
This means we no longer need to offer the cross-sompiler selection in
the menuconfig.

Currently, newlib is built in the start_file step, which is wrong, but was

In case we build a baremetal compiler, use the standard passes:
- core_cc is used to build the C library;
- as such, it is meant to run on build, not host;
- the final compiler is meant to run on host;
As the current final compiler step can not build a baremetal compiler,
call the core backend from the final step.
NB: Currently, newlib is built during the start_files pass, so we have
to have a core compiler by then... Once we can build the baremetal
compiler from the final cc step, then we can move the newlib build to
the proper step, and then get rid of the core pass-1 static compiler...

Currently, we issue the bare-metal compiler from the pass_1 & pass_2
core compilers, because the final gcc breaks while doing so.
This implies we have to build some libces during the start_files step,
instead of the standard libc step. This is the case for newlib.
By adding a backend/frontend infra to the final gcc, we can abstract
what backend to call: the standard backend for non-bare-metal gcc,
and the core backend for bare-metal.

frontend without changing the way bare-metal is built, to come in a

Dumping the backtrace has been broken since changeset #652e56d6d35a:
scripts: execute each steps in a subshell
We can spawn sub-sub-shells in some cases.
The way the fault handler works is to dump the backtrace, but to avoid
printing it once for every sub-shell (which could get quite confusing),
it simply exits when it detects that it is being run in a sub-shell,
leaving to the top-level shell the work to dump the backtrace.
Because each step is executed in its own sub-shell, the variable arrays
that contain the step name, the source file and line number, are lost
when exiting the per-step sub-shell.
Hence, the backtrace is currently limited to printing only the top-level
main procedure of the shell.
Fix this thus:
- when dumping the bckatraces for the steps & the functions, remember
it was dumped, and only dump it if it was not already dumped
- at the top-level shell, print the hints
Also, rename the top-level step label.
