[elbe-devel] UEFI support

[Yegor Yefremov]

I need an image for x86_64 to be able to boot in both BIOS and UEFI
environments. I cannot use ELBE 3.0 as I'm blocked by this issue [1].
So I've backported following patches to ELBE v2.3:

Add examples for UEFI boot with grub
Add support for hybrid images (UEFI+Bios)
hdimg: change mountpoint of efi partition to /boot/efi
Add support for UEFI boot with grub
hdimg: do not use flag lba if partition format is gpt

I've stopped my VM, removed initvm folder and recreated initvm via:

./elbe initvm --skip-build-bin --skip-build-sources create --directory=initvm

But when I try to create image, I get following error, i.e. the new
code won't be used by the initvm.

Build failed

What am I making wring?
