Olivier, thanks a lot for your suggestion, it's indeed exactly the
problem I suffered. I've rebuilt world with
WITH_LLVM_LINK_STATIC_LIBRARIES= and 'poudriere options' instantly
went back to 16-17 minutes. Meanwhile I also noted world build time
before and after (with ccache running, but CCACHE_DISABLED=true):
>>> World build completed on Fri Mar 13 22:39:17 EET 2026
>>> World built in 6202 seconds, ncpu: 8, make -j6

>>> World build completed on Sat Mar 14 03:06:36 EET 2026
>>> World built in 3730 seconds, ncpu: 8, make -j6

I'm pretty sure ports will build in reasonable time again, just didn't
rebuild poudriere jail yet.
