Subject: [PATCH] Rework how the fdt command builds.

Trying to avoid all variants of:
cat syminfo.lst | sort | gawk -f ../../grub-core/genmoddep.awk > moddep.lst || (rm -f moddep.lst; exit 1)
grub_fdt_install in linux is not defined
grub_fdt_load in linux is not defined
grub_fdt_unload in linux is not defined
grub_fdt_install in xen_boot is not defined
grub_fdt_load in xen_boot is not defined
grub_fdt_unload in xen_boot is not defined
