FWIW this commit somehow has an effect on x86 binary. I can reproduce
it. I've collected what I know so far here:
https://github.com/google/syzkaller/issues/1271#issuecomment-559093018
Well, actually it does not look like effect of this commit but rather
non-deterministic/hermetic kernel build.
+Al for affected x86 build bullshit
