    s390: Deprecate s390 32-bit target "s390-*"
    
    The s390 32-bit target (s390-*) is deprecated and planned for removal
    in a future release, along with the elf32-s390 target format.  Emit an
    error for this target during configure, which can be overridden using
    option --enable-obsolete.
    
    Linux Kernel 6.19 removed s390 32-bit compatibility support. [1]
    Glibc 2.43 [2] and GCC 16.1 (compiler option -m31) [3] deprecated
    s390 32-bit with the intent to remove it in a future release.
    
    The s390 64-bit target (s390x-*) remains supported.
