VSX bit is enabled by default for Power7 and Power8 CPU models,
so we need to disable them in order to avoid instruction exceptions.
Kernel will activate it when necessary.
* grub-core/kern/powerpc/ieee1275/startup.S: Disable VSX.

* configure.ac: Remove -m64 from checks for -mcmodel=large and
-mno-red-zone. These are always either unnecessary (x86_64-emu) or
already in TARGET_CFLAGS at this point, and they produce incorrect
results when building for x32.
* grub-core/kern/x86_64/dl.c (grub_arch_dl_relocate_symbols): Cast
pointers to Elf64_Xword via grub_addr_t, in order to work on x32.
* include/grub/x86_64/types.h (GRUB_TARGET_SIZEOF_VOID_P,
GRUB_TARGET_SIZEOF_LONG): Define to 4 on x32.

is_qemu is not being set lead to disabling of feature like
GRUB_IEEE1275_FLAG_HAS_CURSORONOFF. This resulted in cursor not being
displayed during the grub-menu edit.

This patch adds bi-endian support for both 32-bit and 64-bit elf files.
It compares the native endianness to the endianness of the elf file, and
swaps the header bytes if necessary. This will allow, for example,
32-bit Big Endian grub to load a 64-bit Little Endian kernel.

If this option is enabled, then do all of the following:
Don't display introductory message about line editing unless we're
actually offering a shell prompt. (This is believed to be a workaround
for a different bug. We'll go with this for now, but will drop this in
favour of a better fix upstream if somebody figures out what that is.)
Don't clear the screen just before booting if we never drew the menu in
the first place.
Remove verbose messages printed before reading configuration. In some
ways this is awkward because it makes debugging harder, but it's a
requirement for a smooth-looking boot process; we may be able to do
better in future. Upstream doesn't want this, though.
Disable the cursor as well, for similar reasons of tidiness.
Suppress kernel/initrd progress messages, except in recovery mode.
Suppress "GRUB loading" message unless Shift is held down. Upstream
doesn't want this, as it makes debugging harder. Ubuntu wants it to
provide a cleaner boot experience.
