Thanks for submitting. I don't find the post-image-efi-gpt.sh script
really nice, but since genimage currently doesn't have GPT partition
table support, that's pretty much all what can be done, and it's good
to have an example in Buildroot.

Therefore, if there is no opposition against this patch within the next
days, I will apply it.

Thanks!

Thomas
