安装gcc-10-aarch64-linux-gnu，除了libexpat.so.1和libz.so.1剩下的动态链接库都在/usr/aarch64-linux-gnu/lib。顺便说一下可以用apt-file search搜索文件所在的package。

libpthread.so.0
libdl.so.2
libutil.so.1
libm.so.6
libexpat.so.1
libz.so.1
libc.so.6
ld-linux-aarch64.so.1

然后用patchelf修改interpreter和rpath（参考Android运行Linux程序）。因为python安装的位置不是/usr/bin所以要设置PYTHONPATH，然后就可以在Android上使用python了。
