  1. wasm: init cross target 

    Adds pkgsCross.wasm32 and pkgsCross.wasm64. Use it to build Nixpkgs
with a WebAssembly toolchain.

stdenv/cross: use static overlay on isWasm

isWasm doesn’t make sense dynamically linked.

  3. wasmtime: init and use for emulation 

    This isn’t really an "emulator" but it’s the closest concept we have
right now.

  7. compiler-rt: Don't try to build a test executable 

    Got this trick from stack overflow to avoid needing compiler-rt to link
the test exe before building compiler-rt. a static lib isn't linked at
all, and so breaks the cycle.

  10. wasilibc: use .imports file for lld 

    instead of passing in the --allow-undefined-file, we can just let lld
find the file.
