When the Linux Kernel image does not include the EFI stub [1],
Grub2 EFI linux loader fallback to the legacy i386 loading.
See [2] [3]. Grub 2.14 enabled the NX compatible for the EFI
image in [4].
When booting a Linux Kernel without the EFI stub with Grub 2.14 with
NX flag, the boot fails before starting the kernel with a EDK2 page
fault error [5]:
!!!! 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 commit adds CONFIG_EFI_STUB to board/pc/linux.config to make sure
grub will load the Kernel using its efi loading code.
This commit is needed with EDK2 with NX protection enabled and
Grub 2.14 also enabling NX.
