It seems, /usr/lib/aarch64-linux-gnu/libcrypto.a is built without -fPIC. From where the library comes? It is quite unusual to see a library built without -fPIC in a Linux distribution that is released somewhere in a last ten years at least, because it means that the library can't be used in any -fPIC (dynamic library) or -fPIE (executable) code. Linux distros also use -fPIE by default for years.

I mean, if it comes from distro's repositories, it can be considered as the problem in the package and worth a notice for its maintainers.
