--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Please fix this in GCC by defaulting to --enable-initfini-array for a much 
wider range of configurations (including all *-*-linux* and *-*-gnu*, for 
example, if not all ELF configurations) for cross compilation, rather than 
only in the native case; build-many-glibcs.py is not a good place to fix a 
GCC issue.

I opened

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100896

In the meantime, --enable-initfini-array should be passed to GCC configure.

    Configure GCC with --enable-initfini-array [BZ #27945]

    Starting from GCC 12, the .init_array and .fini_array sections are enabled
    unconditionally by

    commit 13a39886940331149173b25d6ebde0850668d8b9

        Always enable DT_INIT_ARRAY/DT_FINI_ARRAY on Linux

    configure GCC with --enable-initfini-array to enable them when using GCC
    release branches.

    Fixes BZ #27945.
