It seems the issue is that the bot is using Make instead of Ninja for building,
and clangd Make has a hardcoded path to shell (which is probably in /usr/bin on the bot in question).
Sylvestre, could you reconfigure the bot to use Ninja?

Looking at the results it seemed like there were a good amount of true positive hits but the last run looks like it was in April. That's long enough that the results are not very useful for identifying bugs in code you own, or for that matter filing bugs against FPs in checkers.
