This failure is what I would expect if your compiler does not have the
fix.  Can you see if your gcc includes this change?

commit 5d8b60effc7268448a94fbbbad923ab6871252cd
Author: Eric Botcazou <ebotcazou@adacore.com>
Date:   Wed Jan 10 13:23:46 2024 +0100

    Fix debug info for enumeration types with reverse Scalar_Storage_Order
    
    This implements the support of DW_AT_endianity for enumeration types because
    they are scalar and therefore, reverse Scalar_Storage_Order is supported for
    them, but only when the -gstrict-dwarf switch is not passed because this is
    an extension.
    
    There is an associated GDB patch to be submitted to grok the new DWARF.

thanks,
Tom
