Did some testing. Previously pretty much everything I tried failed.
I don't have mcf, but git, less, gcc LTO+autofdo bootstrap all appear to work

Richard Biener:
I think they become deterministic with -frandom-seed=0 for example.
They are not deterministic to support partial linking

Test case
git clone https://github.com/andikleen/linux-misc -b lto-linus-3.15
Build with the attached kernel config (copy to .config in the build dir) and
