When one of the linking passes fails, additional intermediate files are
still in place. Having them available for analysis of the underlying
problem can be pretty helpful. Collect some into a new intermediates/
directory. (Nothing new will be collected if linking succeeds.)
As the script is run with -e passed to bash, defer exit if the main
"make" (or substituent script thereof) failed. This way more artifacts
are collected, potentially making it easier to analyze the failure.

A recent update to qemu-xen has bumped the build requirements, with Python 3.8
being the new baseline but also needing the 'ensurepip' and 'tomllib/tomli'
packages.
* Ubuntu/Debian package 'ensurepip' separately, but it can be obtained by
installing the python3-venv package.
* 'tomllib' was added to the python standard library in Python 3.11, but
previously it was a separate package named 'tomli'.
In terms of changes required to build QEMU:
* Ubuntu 24.04 (Noble) has Python 3.12 so only needs python3-venv
* Ubuntu 22.04 (Jammy) has Python 3.10 but does have a python3-tomli package
that QEMU is happy with.
* FreeBSD has Python 3.9, but Python 3.11 is available.
In terms of exclusions:
* Ubuntu 20.04 (Focal) has Python 3.8, but lacks any kind of tomli package.
* Fedora 29 (Python 3.7), OpenSUSE Leap 15.6 (Python 3.6), and Ubuntu
18.04/Bionic (Python 3.6) are now too old.
Detecting tomllib/tomli is more than can fit in build's one-liner, so break it

former sets 'debug' variable to 'y' and the latter to 'n'. This variable

As a corollary, we end up building/testing Xen with CONFIG_DEBUG always
set to a default value ('y' for unstable and 'n' for stable branches),
regardless of the type of the build job.
Fix this behavior by setting CONFIG_DEBUG according to the 'debug' value.

Currently, all the arm64 defconfig build jobs, regardless of the
container used, end up building Xen with the extra config options
specified in the main build script (e.g. CONFIG_EXPERT,
CONFIG_STATIC_MEMORY). Because these options are only needed for
specific test jobs, the current behavior of the CI is incorrect
as we add the extra options to all the defconfig builds. This means
that on arm64 there is not a single job performing proper defconfig build.
To fix this issue, add custom build jobs each time there is a need for
building Xen with additional config options. Introduce EXTRA_XEN_CONFIG
variable to be used by these jobs to store the required options. This
variable will be then read by the main build script to modify the .config
file. This will also help users to understand what is needed to run specific
