AFAICS, nothing in config.sub, and the different configure scripts in binutils-gdb select on *-x32-*. ISTR that a triplet like x86_64-*-linux-gnux32 or x86_64-*-linux-gnu-x32 was originally proposed, but then the toolchain ended using strictly multilib flags to select/detect x32. But, actually, now that I grep, I find a few hits on "x86_64-*-linux-gnux32", though not many, so it looks like there's a triplet after all. Thanks, Pedro Alves
