My suspicion is that "actual" will have size 0 for you. If that's the
case, I'd suggest running the commands from the "check-chainlint"
target in t/Makefile manually one at a time to see if you can figure
out which is failing. For instance:

    % ./chainlint.pl --emit-all chainlinttmp/tests
This reminded me of an earlier report in which chainlint.pl was
producing no output for "actual" on Linux for s390x processors. That
was due to /proc/cpuinfo producing results which the script wasn't
expecting. It was fixed by 1f51b77f4f (chainlint.pl: fix /proc/cpuinfo
regexp, 2022-11-22)[1]. At the time of that patch, I noted[2]:
Yeah, the output for /proc/cpuinfo is not standardized across architectures,
unfortunately.
    A separate problem is that chainlint.pl doesn't fall back to a
    sensible non-zero value if ncores() returns 0 (or some other
    nonsense value). That is, of course, outside the scope of the
    well-focused problem fix which this standalone patch addresses. I
    may end up submitting a fix separately to make it fall back
    sensibly.

which probably explains the behavior you're experiencing. To fix it,
we'll need to see the output you get from:

    cat /proc/cpuinfo
Here you go:
