    x86-64: Add GLIBC_ABI_GNU2_TLS version [BZ #33129]

    Programs and shared libraries compiled with -mtls-dialect=gnu2 may fail
    silently at run-time against glibc without the GNU2 TLS run-time fix
    for:

    https://sourceware.org/bugzilla/show_bug.cgi?id=31372

    Add GLIBC_ABI_GNU2_TLS version to indicate that glibc has the working
    GNU2 TLS run-time.  Linker can add the GLIBC_ABI_GNU2_TLS version to
    binaries which depend on the working GNU2 TLS run-time:

    https://sourceware.org/bugzilla/show_bug.cgi?id=33130

    so that such programs and shared libraries will fail to load and run at
    run-time against libc.so without the GLIBC_ABI_GNU2_TLS version, instead
    of fail silently at random.

    This fixes BZ #33129.
