bug#72429: CLISP build failure on kernel-updates / blocks linux-libre

[Leo Famulari]

While testing the recent kernel updates [0], I noticed that all builds
on the 'kernel-updates' branch fail on aarch64-linux:

https://ci.guix.gnu.org/eval/1528394?status=failed

As shown in the build log for linux-libre-5.4.281 [1], the tests fail:

------

I don't understand why CLISP needs to be rebuilt now. But it's blocking
the kernel updates now.

Any ideas?
