wasmtime-jit fails to built when compiled standalone

[marmistrz]

The compilation succeeds if cargo build is executed from the repository root, but fails if cargo build is executed from wasmtime-jit. Tested on Arch Linux, nightly. (feature(alloc) may not be used on stable)

$ cd wasmtime-jit
$ cargo build
