ERR_get_error_all()[1] is a openssl v3 API, so to make code
compatible with openssl v1 utilize ERR_get_err_line_data
instead. Since openssl is already a build requirement for
the kernel (minimum requirement openssl 1.0.0), this will
allow bpftool to compile where opensslv3 is not available.
Signing-related BPF selftests pass with openssl v1.

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 reStructuredText 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.
