Looking good, but I do not know if it is requested to be "consistent" with FreeBSD check style, e.g. getconf GNU_LIBC_VERSION | awk '{print 2ドル}' | cut -d. -f2. cc @iluuu1994

CentOS 7 is 11 years old and EOL for >1 year

There are so much things outdated there, a lot of PHP dependencies are no longer satisfied

I don't see the benefit of maintaining for dead targets

Me neither but it is an "easy" fix and there are still folks using Linux with outdated glibc versions so I though: why not.

An alternative could be to document the workaround we are using currently and that is just adding ax_cv_have_func_attribute_ifunc=no to the arguments for ./configure for PHP 8.5 ZTS on old glibc versions:

$ ./configure ax_cv_have_func_attribute_ifunc=no --enable-zts --other-flags

IDK where to document this, most likely just having this comment posted here might already be enough for folks to find it 😉

I remember Girgias and I had been discussing to level up the minimum os versions for the next major release. It was centos 8, solaris 10 ... for the next 8.6 I believe.
