AFAICS, that "x32" is in the "vendor" part of the triplet, which should
never mean anything for the tools themselves, being a free field to use by
whoever builds the tools, in order to give the binaries a unique
file name (x86_64-x32-linux-gcc, etc.), and for branding, like
x86_64-redhat-linux-gcc. 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.
