我的 `.cargo/config.toml`:
```
[target.riscv64gc-unknown-linux-gnu]
rustflags = [
    "-C", "link-arg=--sysroot=/home/yorling/licheenano-sysroot",
    "-C", "link-arg=-L/home/yorling/licheenano-sysroot/usr/lib/riscv64-linux-gnu",
    # "-C", "link-arg=-L/home/yorling/licheenano-sysroot/usr/lib/riscv64-linux-musl",
    # "-C", "link-arg=-L/home/yorling/licheenano-toolchain/gcc/riscv64-linux-musl-x86_64/sysroot/usr/lib64/lp64",
    "-C", "link-arg=-mcpu=c906fdv",
    "-C", "link-arg=-march=rv64imafdcv0p7xthead",
    "-C", "link-arg=-mcmodel=medany",
    "-C", "link-arg=-mabi=lp64d",
    "-C", "target-feature=+crt-static",
]
# linker = "/home/yorling/licheenano-toolchain/gcc/riscv64-linux-musl-x86_64/bin/riscv64-unknown-linux-musl-gcc"
linker = "/home/yorling/licheenano-toolchain/gcc/riscv64-linux-x86_64/bin/riscv64-unknown-linux-gnu-gcc"
```

其中 sysroot 是我从 nano 上面直接复制下来的：
```
rsync -avz --delete --progress --exclude={"/proc/*","/sys/*","/dev/*","/tmp/*","/run/*","/mnt/*","/media/*","/var/cache/apt/*"} usblicheenano:/ ~/licheenano-sysroot
```

依赖都已安装，并且手动 check 确实存在：
```
midi master* 7s
❯ ls /home/yorling/licheenano-sysroot/usr/lib/riscv64-linux-gnu/crt1.o
/home/yorling/licheenano-sysroot/usr/lib/riscv64-linux-gnu/crt1.o

midi master*
❯ ls /home/yorling/licheenano-sysroot/usr/lib/riscv64-linux-gnu/libasound.so
/home/yorling/licheenano-sysroot/usr/lib/riscv64-linux-gnu/libasound.so
```

编译都没问题，但是最后链接的时候报错：

```

```

有大佬知道是什么问题吗，折腾一天了，还是没有成功😭

核心报错是：
```
cannot find crt1.o: No such file or directory
cannot find -lasound
```
