wasm-pack build failed - linker rust-lld not found

[humb1t]

🐛 Bug description

Generated from https://github.com/rustwasm/wasm-pack-template project failed to be build via wasm-pack build.

1. stable-armv7-unknown-linux-gnueabihf unchanged - rustc 1.37.0 (eae3437df 2019-08-13) failed with:

error: linker `rust-lld` not found
  |
  = note: No such file or directory (os error 2)

error: aborting due to previous error

Which looks like #618 - but recommended fix should be already in stable.

2. nightly-armv7-unknown-linux-gnueabihf unchanged - rustc 1.39.0-nightly (2111aed0a 2019-08-17) failed with:

Thanks for the report! At this time prebuilt rust-lld is only shipped on x86_64 platforms in rust-lang/rust. For non-x86_64 platforms you'll need to arrange for wasm-ld to be pre-installed and you'll have to configure the build to use it (likely using CARGO_TARGET_WASM32_UNKNOWN_UNKNOWN_LINKER=wasm-ld
