Since Buildroot commit [1] (boot/grub2: bump to version 2.14), the
qemu_x86_64_efi_defconfig fails at boot time with the error:
!!!! X64 Exception Type - 0E(#PF - Page-Fault) CPU Apic ID - 00000000 !!!!
ExceptionData - 0000000000000003 I:0 R:0 U:0 W:1 P:1 PK:0 SS:0 SGX:0
This issue happens because EDK2 and Grub 2.14 are enabling NX and the
kernel lacks the CONFIG_EFI_STUB configuration. For the full explanation
see the commit log of [2] (board/pc/linux.config: enable CONFIG_EFI_STUB).
This commit enables CONFIG_EFI_STUB=y.
