I tried to upgrade from 1.50.0 nightly to the latest 1.52.0 but I can't compile my crate anymore and I getting the following error:

error: linking with `rust-lld` failed: exit code: 1

Any idea what's causing this and how it can be fixed?

I thought it might be related to the wasm-bindgen version, and upgraded to 0.2.71 but that's not fixing it.

Fix build of raytrace example on nightly

The `__wasm_init_memory` function is no longer exported and we also need
to build with `+mutable-globals`.

Closes rustwasm#2487

LLVM 12 landed and interfaces have changed. The build flags need to be updated but a few other things need fixing as well. I'd recommending using older nightlies until things have settled.
