It looks like Ubuntu added a patch to fix this slightly differently (adding <setjmp.h> to efi/main.c instead of adding <efisetjmp.h>[1]). With that it compiles as well. I don't quite understand the reference to glibc in the changelog[2], though. This is reusing syslinux's internal setjmp logic copied from klibc while gnu-efi rolled its own. It's also possible that by including the "wrong" header you get the wrong linkage against the wrong implementation. Could you try this out? Apparently I cannot test this within qemu OVMF (per [3] and it also didn't boot for me).
