FWIW, in OSSTest, we are chainloading Xen from GRUB. I have tried to 
chainloading on QEMU but couldn't get to work so far (even without your 
series).
Although, I have no trouble to boot using the GRUB way (i.e. via multiboot).

IIUC, you are trying to add section into the EFI binary and not the ELF. 
Is it correct?
I don't know what x86 is doing but for Arm, xen.efi (and Linux Image) is 
custom built. So it may lack information to be recognized by objdump.
My knowledge of objdump is fairly limited. If you are interested to fix 
it, then I would suggest to ask the binutils community what they expect.
We could then adapt so objdump can recognize it.
