This issue has been hard to reproduce.

Even when I manually build the same SEABIOS version.

Everything boots for me when manually trying with bellow command

qemu-system-x86_64 \
-bios seabios/out/bios.bin \
-nographic \
-chardev stdio,id=char0,mux=on,signal=off \
-mon chardev=char0,mode=readline \
-serial chardev:char0 \
-drive file=vm-storage/emmc-wic-udoo-bolt-emmc.rootfs.wic,format=raw,if=virtio 

Is there anyway with v3 to soley run 

oe-selftest --verbose -r wic.Wic2.test_grub_install_biosplusefi_qemu.

And paste output?
