Step to reproduce:
rm build/host/stage0* -rf
./x.py check library/std compiler/rustc src/tools/miri
Now Miri fails to build with >1800 errors. The first ones are:

However, if I now run ./x.py check miri, everything is fine. rm build/host/stage0* -rf && ./x.py check miri is also fine. Something about explicitly giving the three paths to build is throwing bootstrap off. And even more strangely, the same sequence of commands worked fine before #116828.
