Bug#1136633: libjxl-devtools: doesn't reproduce as it captures CPU features of the host in the binary

[Paul Gevers]

Package: libjxl-devtools
Version: 0.11.2-3
Severity: normal
User: reproducible-builds at lists.alioth.debian.org
Usertags: cpu

Hi,

I just had a look at why libjxl-devtools and libjxl-tools don't 
reproduce and it seems to capture the CPU features of the host where the 
build runs and embeds it in the binary. Could you have a look and avoid 
it? If it would actually uses these results, your package would very 
likely be violating the Debian baseline for amd64 too.
