Rollup merge of #41940 - est31:master, r=eddyb 

config.toml.example: point out that optimize = false won't speed up a full bootstrap

Originally I've learned about this by @eddyb pointing this out to me over IRC, and after having told someone today the same over IRC I've thought that this is a common mistake and should be prevented by a note in config.toml.example
