Revert GRUB2 patch causing boot failure on some old x86_64 BIOSes (#3324) 

GRUB 2.12 release contains a change of the loader [1] used for loading
the kernel on x86_64 platform. This change was identified to cause boot
failure on some old Intel Atom boards with the NM10 chipset, and
possibly some others. Revert this patch before we get a more proper fix
for the issue.

[1] https://git.savannah.gnu.org/cgit/grub.git/commit/?id=cfbfae1aef0694b416aa199291cfef7596cdfc20

Fixes #3305

Subject: [PATCH] Revert "efi: Use generic EFI loader for x86_64 and i386"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This reverts commit cfbfae1aef0694b416aa199291cfef7596cdfc20.
The generic EFI loader doesn't play well with boards based on Intel
NM10, and possibly some more AMD based boards. Reverting this page
before a proper fix is found is the only way to boot system with GRUB
2.12 on those systems.
Makefile.am is only modified to prevent autoreconf from running, since
GRUB is built from the release tarball and doesn't use autotools.
