[Buildroot] [Bug 10261] Grub2 fails to build for x86_64

[bugzilla at busybox.net]

https://bugs.busybox.net/show_bug.cgi?id=10261

--- Comment #2 from Erico Nunes <nunes.erico@gmail.com> ---
I have done a lot of grub2 builds for x86_64 on Fedora 25 and even recently
tested the pc_x86_64_bios_defconfig and pc_x86_64_efi_defconfig configs on
Fedora 26 as well and did not hit this issue.

Is this a clean build (make clean all)?
Can you please attach a .config file where you see the problem, for us to try
to reproduce it?

Created attachment 7216

Config file

Sorry I thought I had attached the config file, but it turns out it is too
large to attach. So I've bzip2'ed it now

I am able to reproduce the issue with your config, running Fedora 26 if that
matters. Had to remove some of your user specific settings such as ones
pointing to your BR2_EXTERNAL, but nevertheless reproduced:

> 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

I retested and am not able to reproduce a grub2 build failure with
pc_x86_64_efi_defconfig, so it must be one of your changes.

So now we need to narrow down which of your changes caused this, might be the
changes in the grub2 config or more likely some of your optimization settings.

Also we might consider retesting this with the v2 patchset on patchwork at [1]
since it did some better separation between the host part and target part of
grub2 which I wouldn't discard being a cause here (this would be one more
reason to have something like that merged). I plan to respin that for 2017.11.

It turns out that grub2 fails to build with BR2_SSP_ALL=y.
The following defconfig is enough to reproduce the issue:

BR2_x86_64=y
BR2_SSP_ALL=y
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
BR2_TARGET_GRUB2=y
BR2_TARGET_GRUB2_X86_64_EFI=y

We already had Bug 8946 in the past with a very similar issue and from which we
can borrow a solution. So I sent the following patch as an attempt to address
this issue before 2017.08 is cut out:
