Cannot build an (even the simplest) app on ARMv6

Hello,

Using that Dockerfile :
```
FROM rust:1.68
RUN rustup target add arm-unknown-linux-musleabihf
RUN apt update && apt install -y musl-tools musl-dev binutils-arm-linux-gnueabihf gcc-arm-linux-gnueabihf gcc-aarch64-linux-gnu libcap2-bin
RUN ln -s /usr/bin/arm-linux-gnueabihf-gcc /usr/bin/arm-linux-musleabihf-gcc
RUN ln -s /usr/bin/aarch64-linux-gnu-gcc /usr/bin/aarch64-linux-musl-gcc

WORKDIR /build

COPY . .

RUN cargo build --release --target arm-unknown-linux-musleabihf
```

**Works for building the Mimalloc Rust crate directly**, but not when building the simplest example application with :
* Cargo.toml :
```toml
[package]
name = "mimalloc_test"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
mimalloc = "0.1"
```

* main.rs :
```
use mimalloc::MiMalloc;

#[global_allocator]
static GLOBAL: MiMalloc = MiMalloc;

fn main() {
    let _s = String::from("TEST");
    println!("Hello, world!");
}

```

The error is then :
```
