Does anyone have a good docs on how to cross-compile Rust for aarch64 Android target? I have to run it on CI as well as locally. Thanks!

I am trying to cross compile rust. I am able to build and compile the binary successfully, however when i run this binary on aarch64 architecture, i get the following error

```

./crossed: /lib/libc.so.6: version `GLIBC_2.33' not found (required by ./crossed)

./crossed: /lib/libc.so.6: version `GLIBC_2.32' not found (required by ./crossed)

./crossed: /lib/libc.so.6: version `GLIBC_2.34' not found (required by ./crossed)

```

I am not sure what i did wrong. can you please help me out.
I have used the cross-rs tool and it works properly and generates a binary that is working but i am not sure what i am doing wrong. I am using aarch64-unknown-linux-gnu as target compiler

I'm trying to compile Rust code on ubuntu 22 for my Orange Pi zero2 (ubuntu 22 server ARM). As a target, I'm using first-tier support aarch64-unknown-linux-gnu.

My cargo.toml

[package]
name = "pitest"
version = "0.1.0"
edition = "2021"

[dependencies]
actix-web = "4"
btleplug = "0.10.4"
tokio = { version = "1.23.0", features = ["full"] }
local-ip-address = "0.4.9"
openssl = { version = "0.10", features = ["vendored"] }

[[bin]]
edition = "2021"
name = "pi"
path = "src/main.rs"

Compile command:

cargo build --target aarch64-unknown-linux-gnu

Error:

Compiling libdbus-sys v0.2.2
Compiling openssl v0.10.44
Compiling actix-http v3.2.2
error: failed to run custom build command for `libdbus-sys v0.2.2`

  --- stderr
  pkg_config failed: pkg-config has not been configured to support cross-compilation.

  Install a sysroot for the target platform and configure it via
  PKG_CONFIG_SYSROOT_DIR and PKG_CONFIG_PATH, or install a
  cross-compiling wrapper for pkg-config and set it via
  PKG_CONFIG environment variable.
  One possible solution is to check whether packages
  'libdbus-1-dev' and 'pkg-config' are installed:
  On Ubuntu:
  sudo apt install libdbus-1-dev pkg-config
  On Fedora:
  sudo dnf install dbus-devel pkgconf-pkg-config

  thread 'main' panicked at 'explicit panic', /home/lukasz/.cargo/registry/src/github.com-1ecc6299db9ec823/libdbus-sys-0.2.2/build.rs:16:9
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I would like to point out, that I have installed libdbus-1-dev pkg-config

I found on some Chinese websites, that missing dbus-devel may be the problem but there is no such package to download on ubuntu... also hello-world app worked fine.
