      .`glibc` package updated to include bug fixes and enhancements from the upstream 2.39 release

      Upstream development delivered multiple bug fixes and enhancements to `glibc` 2.39. As a consequence, RHEL 10 `glibc` became outdated relative to the upstream release, resulting in gaps in features and unresolved bugs. To address this, the fixes and enhancements from the `glibc` 2.39 upstream release branch were backported to RHEL 10. As a result, RHEL 10 `glibc` now provides feature and bug parity with the upstream `glibc` 2.39 release branch as of August 20, 2025.

    elf: Preserve _rtld_global layout for the release branch
    
    Backporting commit 97017da5ef946c6d38c252f56c8cb7c205b732fa
    ("elf: Introduce _dl_debug_change_state") removed the
    _ns_debug member.  Keep it to preseve struct layout.

      The upstream backports will help to close the gap relative to RHEL 9.
