It won't run on 32-bit only systems.

The preprocessor macro test is __x86_64__ and __ILP32__

I wasn't exactly sure where to put it, but ld.so --help gave the output
with the glibc-hwcaps optimization paths exactly like x86_64-linux and
pretty much every other piece of software which needed adjusting for it
stressed that it was x86_64.

There's a #debian-x32 channel on libera.chat, they might have some
suggestions about tagging it as 32-bit or 64-bit.  As-is it's currently
labeled as 64-bit.
