texlive-latex-amscls-44951 fails to build non-deterministically

[Ludovic Courtès]

Hi!

On 05c62b1e1d34ec8e68de3f1d3d7a7218ef8993d7, texlive-latex-amscls-44591
initially failed to build on i686-linux on berlin (it’s an indirect
dependency of po4a, which Guix now depends on):

(See
<https://berlin.guixsd.org/log/2zlxncnv21a4yp7prh45hr3caaq8p8m0-texlive-latex-amscls-44591>.)

The offending file looks OK though:

--8<---------------cut here---------------start------------->8---
$ file -L /gnu/store/f5i60myfpswi7vqgjcrhh7kc0nc22ks5-libtiff-4.0.9/lib/libtiff.so.5

--8<---------------cut here---------------end--------------->8---

The same thing built successfully on hydra:

  <https://mirror.hydra.gnu.org/log/2zlxncnv21a4yp7prh45hr3caaq8p8m0-texlive-latex-amscls-44591>

I rebuilt texlive-latex-amscls-44591 on berlin and this time it
succeeded.

Has anyone seen this kind of issue before?
