This doesn't work yet, rustup-toolchain-install-master currently cannot be built on windows-arm since it depends on winapi:

rustup-toolchain-install-master v1.8.1 (/home/r/src/rust/rustup-toolchain-install-master)
├── ansi_term v0.12.1
│   └── winapi v0.3.9
...
├── pbr v1.1.1
│   ├── crossbeam-channel v0.5.15
│   │   └── crossbeam-utils v0.8.21
│   ├── libc v0.2.174
│   └── winapi v0.3.9 (*)

Might be relevant for rust-lang/rfcs#3817

@kennytm judging from a8m/pb#123 it seems like actually kennytm/rustup-toolchain-install-master#61 is enough to fix this... any chance you could cut a release?

Okay, that seems to work. :) But it is super slow.

There seems to be some behavior difference between x86-win32 and arm-win64 somewhere which lead to things breaking if we use canonicalize here. 🤷

After disabling GC_STRESS, the runtime is reasonable. So, the runner seems to be pretty slow, but that's a problem with all Windows runners.
