[Bug] Failed to compile under linux powerpc64le #1471

Open runlevel5 opened 6 months ago

I ran into following error when trying to compile under Linux powerpc64le:

It would be awesome if this architecture is supported

This will need Cranelift support first: https://github.com/bytecodealliance/wasmtime/issues/1183
