scripts: fix dumping execution backtrace

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.

    18       Linaro is maintaining some advanced/more stable/experimental versions

    19       of gdb, especially for the ARM architecture.

    20 

    21       Those versions have not been blessed by the gdb community (nor have they

    22       been cursed either!), but they look to be pretty much stable, and even

    23       more stable than the upstream versions. YMMV...

    24 

    25       If you do not know what this Linaro stuff is, then simply say 'n' here,

    26       and rest in peace. OTOH, if you know what you are doing, you will be

    27       able to use and enjoy :-) the Linaro versions by saying 'y' here.
