Cannot build to emscripten target with strict mode enabled.

I tried this code:

fn main() {
    println!("Hello, world!")
}

with following config.toml

[target.wasm32-unknown-emscripten]
rustflags = [
    "-C",
    "link-arg=-lnodefs.js",
    "-C",
    "link-arg=-lnoderawfs.js",
    "-C",
    "link-arg=-sALLOW_MEMORY_GROWTH",
    "-C",
    "link-arg=-sEXIT_RUNTIME=1",
]
runner = "node"

[env]
EMCC_STRICT="1"
RUST_BACKTRACE="1"

I expected to see this happen: Compile and run successfully.

Instead, this happened: Failed with undefined symbols exported.

Reproduce the failure with the shown cargo +nightly run -Zbuild-std command, config.toml, and wasm32-unknown-emscripten target. Start by examining the emcc invocation and undefined-symbol errors under EMCC_STRICT=1; done means the minimal Hello World project builds and runs successfully in strict mode.
