This commit enables the arm-uboot, arm-efi and aarch64-efi grub2
platforms in Buildroot.
With the uboot platform, the grub2 image gets built as a u-boot image
and is loaded from u-boot through a regular "bootm". The only
requirement from the u-boot side in order to allow this is that u-boot
is built with CONFIG_API enabled. CONFIG_API seems to not be enabled
by default in most in-tree configurations, however, it seems to be
available for quite some time now. So it might be possible to use this
even on older u-boot versions. This is available only for arm
(32-bit).
With the efi platform, grub2 gets built as an EFI executable. This
allows EFI firmware to find and load it similarly as it can be done
for x86_64. Also, since u-boot v2016.05, u-boot is able to load and
boot an EFI executable, so the uboot efi platform can also be used
from u-boot in recent versions. This has been enabled (mostly) by
default for ARM u-boot. efi platform is available for both arm and
aarch64.

grub2 requires the host grub2-mkimage tool to build some of its target
images. The current way of building this tool in the grub2 package is
to perform a simultaneous host-tools/target-bootloader build during
the grub2 build step.
This method makes the recipe complex to understand, and proved to be a
complication during the work to enable grub2 support for architectures
other than x86.
This patch tries to do a better separation between the build of grub2
host tools and target boot loader image, as a partial step to enable
grub2 to build for other architectures.

In commit 2a27294e9a ("grub2: force
-fno-stack-protector in CFLAGS"), a fix was made to the grub2 package
to make it build properly even when SSP support is enabled.
However, commit 20a4583ebf ("security
hardening: add RELFO, FORTIFY options") reworked how SSP options are
passed, and they are now passed in CPPFLAGS instead of CFLAGS, making
the fix introduced by 2a27294e9a no
longer operating.
This commit will force no-stack-protector in CPPFLAGS instead of
CFLAGS.

grub2 fails to configure when BR2_SSP_ALL is enabled, with the following
configure error:
checking whether -fno-asynchronous-unwind-tables works... yes
checking whether -fno-unwind-tables works... yes
checking for target linking format... unknown
configure: error: no suitable link format found
This can be worked around by enforcing -fno-stack-protector in the
package CFLAGS in a way that overrides the SSP flag, as is already done
for the valgrind package.

As discussed in the mailing list, grub2 usage notes were growing too big
for a Config.in documentation, and so it was agreed that a readme.txt in
the package directory is a better place to put them.
This commit simply moves the documentation as-is to preserve the
original contents as they were in Config.in which can be worked on in
further commits.

After many years since the last release and a long time with grub 2.02
in beta, there is finally a release and it brings many bug fixes and
interesting features such as support for ARM.
Patch boot/grub2/0001-remove-gets.patch doesn't seem to be required
anymore as grub-core/gnulib/stdio.in.h has changed significantly since
"053cfcd Import new gnulib." and has another treatment for gets.
Patch
boot/grub2/0002-grub-core-gettext-gettext.c-main_context-secondary_c.patch
was a backport which is present after the bump and therefore is also no
longer necessary.
Since we're adding a Config.in comment, we also introduce a
BR2_TARGET_GRUB2_ARCH_SUPPORTS hidden boolean, in order to avoid
repeating the architecture dependencies.

Curently, we have a choice to select between stripping and not
stripping. This is legacy code from back when we had a third option,
sstrip (super-strip).
Since we removed sstrip, stripping or not stripping is now just a
boolean rather than a choice.
Make it so.
We make BR2_STRIP_strip default to 'y' to keep the current behaviour of
defaulting to stripping.
Move BR2_STIP_none to legacy, and instruct the user to review the new
setting.
Drop any reference to BR2_STRIP_none in comments.

grub2's build system interprets CC, CFLAGS and CPPFLAGS as for the host
and uses TARGET_CC etc. for the target. However, NM, OBJCOPY and STRIP
are used for the target. We currently pass the host-versions of these
tools as part of $(HOST_CONFIGURE_OPTS).
While we're at it, also pass TARGET_LDFLAGS.
This problem had not been noticed up to now because usually we build on
an x86 machine for the x86 architecture, so the binutils are compatible.
However, this is not true on an i386 when building for x86_64.

In order to support ISO9660 bootable images that rely on Grub 2, this
commit modifies thr Grub 2 makefile to generate and install an El
Torito image. Such an image is simply produced by concatenating the
cdboot.img provided by Grub 2, and the Grub 2 image generated by
Buildroot using grub-mkimage.
Since this action is so simple and cost-free, we don't bother adding a
Grub 2 sub-option for that, and simply generate the El Torito image
unconditionally.

The help text of grub2 explains the detailed steps to create a disk
image with grub2 installed on it. However, the steps for the
BIOS-based systems have a few minor issues fixed by this patch:
- When calling partx to get the partitions detected, we should do it
on the /dev/loop0 block device, and not on the underlying disk.img
image file.
- The grub-bios-setup utility must be called as root to work properly
on /dev/loop0.
- The steps to cleanup the partx and loop device were missing.

Grub 2 has been marked BROKEN in June 2010, and nobody cared to fix it
since then.
At that time, it was marked broken because the build process needed a
Ruby interpreter available on the host, and it's really a pain that
building a bootloader needs such a thing.
I've tried to upgrade the package to Grub2 1.99-rcX, and now it does
not need a Ruby interpreter anymore, but instead requires a tool
called "autogen", which itself needs the Guile Scheme interpreter.
Since we haven't heard any complaints about Grub2 being marked broken,
and since it's such a pain to package, let's get rid of it. Of course,
anybody interested in Grub2 is invited to contribute a working
package.
