The goal of this series is to remove Avocado as a dependency for running
the reverse_debugging functional test.
This test, the last one I’m aware of that relies on Avocado, requires it
because of the need for GDB to test reverse stepping and continue.

I gave it a try, but this did not work for me, the test was not run
at all anymore. Are there any patches needed on top?
hmm that's odd. I'm able to run it with 'make check-functional' and with
'meson test'...
This is how I'm running it (let me know if I'm missing something):

I tried a couple of times now, and finally realized that it's the
"gdb-multiarch" binary that is missing on Fedora. And as far as I can see,
there is also no package that provides this on Fedora? So if we go ahead
with your patches, this test will only run on certain distros that provide
this binary.
'gdb-multiarch' is a command name invented by Debian.
On Fedora, the regular 'gdb' binary is built with support for
multiple architectures for the purpose of remote debugging.
The set of archs supported by GDB in Fedora is
s390-linux-gnu
powerpc-linux-gnu
arm-linux-gnu
aarch64-linux-gnu
riscv64-linux-gnu
x86_64-redhat-linux-gnu
you can query this with 'gdb --configuration' and parsing the
'--enable-targets' args - I've not found a better way :-(
Thanks a lot for checking it closely.
We already detect it via:
source_path/scripts/probe-gdb-support.py
in configure to detect the arches. That's what Alex is suggesting,
to use the gdb from configure in the test harness or scripts that
rely on GDB.
Cheers,
Gustavo
