grub2/0137-Make-it-so-we-can-tell-configure-which-cflags-utils-.patch

Update to grub 2.04 
This change updates grub to the 2.04 release. The new release changed how
grub is built, so the bootstrap and bootstrap.conf files have to be added
to the dist-git. Also, the gitignore file changed so it has to be updated.

Since the patches have been forward ported to 2.04, there's no need for a
logic to maintain a patch with the delta between the release and the grub
master branch. So the release-to-master.patch is dropped and no longer is
updated by the do-rebase script.

Also since gnulib isn't part of the grub repository anymore and cloned by
the boostrap tool, a gnulib tarball is included as other source file and
copied before calling the bootstrap tool. That way grub can be built even
in builders that only have access to the sources lookaside cache.

Resolves: rhbz#1727279

Subject: [PATCH] Make it so we can tell configure which cflags utils are built
with
This lets us have kernel.img be built with TARGET_CFLAGS but grub-mkimage and
friends built with HOST_CFLAGS. That in turn lets us build with an ARM compiler
that only has hard-float ABI versions of crt*.o and libgcc*, but still use soft
float for grub.efi.
