Because the user-emulator binaries are specifically
"implement this kernel ABI", which includes not just
the general CPU architecture but also whether it is 64
bit or 32 bit. You can see this also on other architectures
like qemu-arm and qemu-aarch64. It's also why there are
lots of mips user-mode emulators: qemu-mips, qemu-mipsel,
qemu-mipsn32, qemu-mipsn32el, qemu-mips64, etc, etc:
these all represent different and incompatible ABIs.

If you want to run a guest program built for the 32-bit
x86 ABI, use qemu-i386.
