M1 pre-built binary

[ricochet]

Feature

Add pre-built binaries for M1 and other arm architectures. The following message occurs when running intall.sh on a 2020 macbook pro. I see aarch64 is already available in the github workflow so perhaps only aarch64-apple-darwin is needed.

curl https://wasmtime.dev/install.sh -sSf | bash

Error: Sorry! Wasmtime currently only provides pre-built binaries for x86_64 architectures.

Benefit

The demand for m1 support will only grow with time.

Implementation

It looks like we only need to add a cross-compile target in the github workflow.

I searched for arm related github issues and only found a few

• Can't unwind wasm frames on aarch64-darwin with system libunwind #2808
• lldb: address 0x0000000100000000 maps to more than one section #2127
• Cranelift: implement PIC relocations on AArch64 #2907
• Support PLT entries in cranelift-jit crate on aarch64 #2735

IMO the above bugs shouldn't prevent releasing a binary.

We've now released Wasmtime 0.37, which includes the change in #3983 to build aarch64-apple-darwin binaries, and just now we added the platform to the install.sh script at wasmtime.dev (bytecodealliance/wasmtime.dev#13). Given that, I think we can call this complete and close it!
