[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=784f7aa3981ef6d2c75eeed3aa5de7a5f2ab5fcf
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2023.08.x

apache uses pkgconfig to find dependencies such as lua, nhgttp2, openssl
and systemd.
For openssl, pkgconfig is used since version 2.1.1 and
https://github.com/apache/httpd/commit/0d4387dedc4ad83460bf52fc326c475c64133634
resulting in the following build failure since at least bump to version
2.4.54 in commit 78e5a9c40e0754bbe840ef7b8da85efc28eb8b48:
