WRAPPER] Add missing libc/selinux/ssl symbols

[yzewei]

Add missing wrapper entries for libc/selinux/openssl symbols used by docker run (use apt/libsystemd).
Provide weak libc fallbacks for strerrorname_np and open_tree on older glibc.
Regenerate wrapper outputs.

box64 apt-get update

# run x86 apt/libsystemd in the container

Some function does not exists. Where did you find them and what needs them?

[ksco]

From the description: it's for docker.

[ptitSeb]

Yet, those 2 functions will not exist in most glibc distributions.
And the signal one needs a GOM anyway.

These symbols are missing when running x86_64 binaries inside a docker container on loongarch with box64.

Thank you for your suggestions. I'm still exploring the box64 project and focusing on problem-solving . I'm glad you pointed out the pr. Thanks again! I will modify them. @ksco @ptitSeb

pidfd_send_signal and pidfd_open are using GOM.

Creating default falback for the new call also, that's nice.

Thank you! I'm really interested in improving support for running x86_64 containers on other architectures. I'll be doing more testing, so apologies in advance if I create a bit of noise with more PRs/Issues in the near future!

We appreciate it if you could maintain a document on how to run x86_64 Docker containers with box64 in docs/.

It's still in the debugging stage, and due to the special nature of Loongarch ABI, I'm using the sysroot of ABI2 to run x86 containers on the physical machine of ABI1. I will come up with a standard way of running it as soon as possible (the reason for this is because the glibc version of ABI1 is too low).
