I can try to enable 32-bit build but I don't have any machine with 32-bit UEFI to test. And our openQA need to check the availability for 32-bit UEFI testing, because for now only 64-bit OVMF can be used for testing. The other obstacle is UEFI secure boot, shim only provides 64-bit build and I'm not aware any plans on 32-bit support. We need to also check efi kernel boot stub for 32-bit to decided to go with linux or linuxefi command for booting linux kernel. If the decision is efi boot stub in order to keep our configuration consistent for 32 and 64bit, we need to fix linuxefi to be able to build and work on 32-bit. Currently we can only offer linux command to boot the kernel if without doing any changes to existing source and no secure boot support at all.
