When a computer does not boot at all or the result is only a deep black screen,
a very useful option can be to use a serial connector to get UART debug console
and read it, looking for any useful hint. However, enabling UART debug console
with a sufficient level of details slows down the boot process in most cases.
This commit adds the capability to build debug images, using a special
configuration file for coreboot with debug options. This is a simplistic way
that works for now, but should be improved later on.
These debug images will be generated in the bin-dbg/ directory instead
of bin/ where regular images are located.

Without that fix we have the following issue on PureOS byzantium:
$ resources/packages/coreboot/distclean
resources/packages/coreboot/distclean: 19:
resources/packages/coreboot/../../scripts/tasks/distclean.sh:
Bad substitution
resources/packages/coreboot/distclean: 20: .:
cannot open /../../..//resources/scripts/misc/sysexits.sh:
No such file
This happens because packages/coreboot/distclean uses #!/bin/sh and
that the default sh shell isn't using bash:
$ readlink $(which sh)
dash
and using bash instead works fine:
$ bash resources/packages/coreboot/distclean ; echo $?
0
all the other distclean scripts in packages/*/ have exactly the same
issue. The tests/distlean script is also affected since it also
sources the distclean task.
So we use #!/usr/bin/env bash as it work with both Guix and regular
more or less FHS compliant distributions.
This issue was introduced by the commit
c7e28dc660 ("packages: Add distclean").

The various scripts present in GNU Boot are very fragile, so it's a
good idea to have a pristine GNU Boot source code for making releases.
The issue is that 'git clean -dfx' doesn't remove existing git
repositories like coreboot/ grub/ etc, so we need additional code to
take care of that.

The various build scripts are scattered around in multiple
places. This make it hard for contributors to understand what they
need to modify.
Most GNU Boot users are interested in running GNU/Linux or BSD
operating systems. And the way to install software on these
operating systems is through a package manager. So most users and
contributors already know the package manager abstraction.
So using that abstraction makes it easier to find where things are.
The scripts to install dependencies don't really fit the new structure
but for now we move them in to make sure that everything works
fine. This could be fixed later on and migrated to a single
dependencies packages by auto-detecting the distribution with
/etc/os-release.
