I'm hitting likely the same with Ubuntu 20.04, but not under Debian testing.
It seems that the .note.gnu.property section is interfering with objcpy and
causes the "JHSYST" identification to be removed from the .cell.
Removing the section while copying the .o fixes the issue:
objcopy --version
GNU objcopy (GNU Binutils for Ubuntu) 2.34
readelf -a jailhouse/configs/x86/qemu-x86.o
...
Displaying notes found in: .note.gnu.property
Owner Data size Description
GNU 0x00000010 NT_GNU_PROPERTY_TYPE_0

hexdump -C jailhouse/configs/x86/qemu-x86.cell
