[Xen-devel] [PATCH v2 2/2] Use grub-file to figure out whether multiboot2 should be used for Xen.gz

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

The multiboot2 is much more preferable than multiboot. Especiall
if booting under EFI where multiboot does not have the functionality
to pass ImageHandler.

v2: Rebase on top of  d33045ce7ffcb7c1e4a60c14d5ca64b36e3c5abe
v3: Add 'else' in the conditional.
    Use a tab and four spaces instead of two tabs.
