Andrii Nakryiko b82bb1ffbb selftests/bpf: Add CO-RE relos and SEC("?...") to linked_funcs selftests
Enhance linked_funcs selftest with two tricky features that might not
obviously work correctly together. We add CO-RE relocations to entry BPF
programs and mark those programs as non-autoloadable with SEC("?...")
annotation. This makes sure that libbpf itself handles .BTF.ext CO-RE
relocation data matching correctly for SEC("?...") programs, as well as
ensures that BPF static linker handles this correctly (this was the case
before, no changes are necessary, but it wasn't explicitly tested).

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
