trying 4.7.X instead it actually looks very reasonable now.
Using -flto=jobserver -fuse-linker-plugin -ftime-report -O3 -march=native
-ffast-math -g -ffree-form
I get CP2K to build in 4min on a 32 cores server. The time report also looks
OK. I'll close this PR as fixed (to issue with 4.8 is tracked in PR 45586).
