[Buildroot] grub2

[Tom Deblauwe]

Hello list,

I am trying to build grub2 with the platform as x86-64-efi. I am
building on Ubuntu 14.04 64bit. My target is i386 atom. This works when
I use an external toolchain from Sourcery codebench 2012.09.

But when I try to build with an internal buildroot toolchain it fails on
the grub2 configure step with an error about gcc not having the
"-mcmodel=large" support. I tried gcc 4.9 and 4.8 and they both didn't
have it compiled in apparently. I have enabled the
BR2_TOOLCHAIN_BUILDROOT_LARGEFILE support so I guessed that was ok then
but it's not working.

  I checked out the master of today, then set the compiler, and then did
an "make toolchain" and then "make grub2". So it's a clean build.
What could be wrong with this?

Best regards,
Tom,
