Thanks for these checks. All I've done with the remaining targets
today (csky-linux epiphany-elf fr30-elf frv-linux ft32-elf m32r-elf mcore-elf
mmix-knuth-mmixware nds32-linux nios2-linux sh-linux visium-elf) was
build crosses (without binutils, so stopped shortly after building cc1),
make a copy of cc1, try expected tweaks in config/*/*.cc around the
TYPE_NO_NAMED_ARGS_STDARG_P uses unless it was clearly unnecessary,
make cc1 again and compare if the c23-stdarg-9.c assembly is any different,
if yes, try to eyeball it if the changes are desired, if the assembly is
unmodified, throw away the changes.
With the changes by others (loongarch, mips, riscv) I hope we are good on
the c23-stdarg-*.c tests on all arches.
