Description

Referred to fix this issue:
https://github.com/greenbone/gvmd/pull/1280/files
https://github.com/coelckers/prboom-plus/pull/130/files

From the release notes of glibc 2.32, https://sourceware.org/pipermail/libc-announce/2020/000029.html

The deprecated arrays sys_siglist, _sys_siglist, and sys_sigabbrev
are no longer available to newly linked binaries, and their declarations
have been removed from <string.h>. They are exported solely as
compatibility symbols to support old binaries. All programs should use
strsignal instead.

Review process to land

1. All tests and other checks must succeed.
2. At least one maintainer must review and approve.
3. If any maintainer requests changes, they must be addressed.
