我有一个github工作流程，可以自动化为i686-pc-windows-gnu目标构建rust应用程序的过程，但是它一直给我这个错误：

error: linking with `i686-w64-mingw32-gcc` failed: exit status: 1

我的项目使用的是gpgme Rust crate，下面是我的github工作流程：

name: Build for i686-pc-windows-gnu

on:
  push:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        target: [i686-pc-windows-gnu]

    steps:
    - uses: actions/checkout@v2
    - name: Install mingw-w64 toolchain
      run: sudo apt-get install -y mingw-w64
    - name: Install gpgme dependencies
      run: |
        sudo dpkg --add-architecture i386
        sudo apt-get -y update
        sudo apt-get -y update && sudo apt-get install -y software-properties-common
        sudo add-apt-repository universe
        sudo add-apt-repository multiverse
        sudo apt-get -y update

        sudo apt-get install -y libgpgme-dev:i386 libgpgme11-dev:i386 libassuan-dev:i386 libgpg-error-dev:i386

    - name: Set up Rust toolchain
      uses: actions-rs/toolchain@v1
      with:
        toolchain: stable
        override: ${{ matrix.target }}

    - name: Build project
      run: |
        rustup target add i686-pc-windows-gnu
        export PKG_CONFIG_ALLOW_CROSS=1
        export PKG_CONFIG_SYSROOT_DIR=$(rustc --print sysroot --target ${{ matrix.target }})
        export PKG_CONFIG_ALLOW_SYSTEM_LIBS=1
        export PKG_CONFIG_PATH=/usr/lib/i386-linux-gnu/pkgconfig

        cargo build --target ${{ matrix.target }}

我试着检查/usr//usr/lib/i386-linux-gnu目录是否存在，它确实存在。
