The SGX userspace SDK can build for 32 & 64 bit, though in Fedora/RHEL I will only build it for 64-bit, but that's not relevant for QEMU's needs anyway. Ultimately we're dropping 32-bit host support for QEMU in general at the end of this year, so we don't need to go out of our way to selectively drop things before then unless they're giving us trouble today.
