[v2,1/1] s390: Deprecate s390 32-bit target "s390-*"
Commit Message
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 deprecated s390 32-bit with the intent to remove it in a
future release. [2]
GCC 16 will deprecate s390 32-bit (compiler option -m31) with the intent
to remove it in a future release. [3]
The s390 64-bit target (s390x-*) remains supported.
