Rollup merge of #141777 - Kobzol:dist-linux-alt-no-pgo-bolt, r=marcoieni

Do not run PGO/BOLT in x64 Linux alt builds

Should unblock rust-lang/rust#131077 and also reduce our CI costs. It seems to run ~1.5h on the x64 larger runner (free runner runs out of disk space, sadly).

Discussed [here](https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Utility.20of.20the.20.60dist-x86_64-linux-alt.60.20job/with/521324477).
