Attached is a rebased version of this patch. Hopefully with a reasonable

just seems to end up restating the variable name...
I've now pushed a version of this with a few cleanups, mostly in
.cirrus.yml. It'll be interesting to see how many additional problems
it finds via cfbot.
I've just discovered that that function __ubsan_default_options() is
incompatible with -fsanitize=hwaddress:

I use clang version 16.0.6, Target: aarch64-unknown-linux-android24.
With just 'return ""' in __ubsan_default_options(), I've managed to run
`make check` (there is also an issue with check_stack_depth(),
but that's another story)...
Best regards,
Alexander
