build on android aarch64

Android上build需要先Installing Debian on Android in Termux

在Android上构建时，需要先Installing Debian on Android in Termux

1. install termux

   https://github.com/termux/termux-app/releases/tag/v0.118.0

2. install proot-distro

   select debian distro

   pkg install proot-distro
   proot-distro install debian
   proot-distro login debian

3. install packages

   remember proot-distro login debian first

   apk update
   apt install clang cmake libelf1 libelf-dev zlib1g-dev

   之后的步骤和在ARM上build上相同

Build on ARM

1. 同步 eunomia-bpf 到本地

   git clone https://github.com/eunomia-bpf/eunomia-bpf.git
   cd eunomia-bpf
   git submodule update --init --recursive --remote

2. 配置环境变量

   export PKG_CONFIG_PATH=/usr/lib/aarch64-linux-gnu/pkgconfig

3. 安装依赖

   apt update
   apt install clang cmake libelf1 libelf-dev zlib1g-dev

4. 修改wasm-runtime/CMakeLists.txt中的WAMR_BUILD_TARGET（may not required）

   change set (WAMR_BUILD_TARGET "X86_64") to set (WAMR_BUILD_TARGET "AARCH64")

5. 编译

   make bpf-loader
   make ecli

6. 检查输出

   root@localhost:~/eunomia-bpf# file ecli/build/bin/Release/ecli
   ecli: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, BuildID[sha1]=eab42b79be75951e3a573aa7c61136239d35c868, for GNU/Linux 3.7.0, with debug_info, not stripped
