Why do you think the problem is in RedOS, not in Glibc?

I propose skipping test for some Glibc version using CMake macro

introduced in the following commit:

commit af0f59da76292f30ff75be1ab01458d47b226995
Author: Sergey Kaplun <skaplun at tarantool.org>
Date:   Wed Dec 4 15:03:56 2024 +0300

     test: fix LuaJIT-tests for old libc version

Otherwise, we will skip this test for always for RedOS.

in RedOS 8 glibc version is 2.36-14:

[root at pony /]# rpm -qa | grep glibc
glibc-common-2.36-14.red80.x86_64
glibc-gconv-extra-2.36-14.red80.x86_64
glibc-langpack-en-2.36-14.red80.x86_64
glibc-langpack-ru-2.36-14.red80.x86_64
glibc-2.36-14.red80.x86_64
glibc-devel-2.36-14.red80.x86_64



Also, why detect_redos() is not in utils.lua?
