In commit 7e0e6e3b86 (toolchain/toolchain-external/toolchain-external-bootlin:
update to 2023.11-1) the TestGrubX8664EFI fails with this error:
# efivar -l
traps: efivar[86] trap invalid opcode ip:7fc187f4c7f4 sp:7fff9bbaa930 error:0 in libefivar.so.1.38[7fc187f4c000+16000]
Illegal instruction
This error can be reproduced by installing other packages like "file".
The 2023.11-1 Bootlin toolchains are built for a corei7 CPU [0], which
is in fact a Nehalem CPU; we switched to the new names in commit
653fa001f3 (arch/Config.in.x86: add "newer" names for several Intel
x86 CPU variants). This means that the Bootlin toolchains may use
Nehalem-specific instructions.
The TestGrubX8664EFI test is also setup for BR2_x86_corei7, so our
executables will also contain Nehalem instructions.
However, the default Qemu x86_64 is not guaranteed to emulate all the
instructions specific to Nehalem, causing runtime issues as reported
above.
A similar issue has been fixed in toolchain-builder by adding Nehalem
cpu emulation on the qemu command line [0].

[yann.morin.1998@free.fr:
- reword the commit log to explain corei7 -> Nehalem equivalence
- note that the toolchain-builder *and* our test target corei7, thus
Nehalem

This commit adds four test cases for Grub:
- Grub i386 legacy BIOS
- Grub i386 UEFI
- Grub x86-64 UEFI
- Grub AArch64 UEFI
There is some overlap with the ISO9660 filesystem test cases, some of
which use Grub, but we found it relevant to have separate test cases
for Grub, which were useful to test Grub in non-ISO9660 situations.
The Grub ARM UEFI case is not tested, as it requires Grub to be
chain-loaded by U-Boot. Implementing this test case is left as an
exercise for the reader.

- use EDK2 to build the OVMF blurbs from source, instead of the
binary blobs
- add host-dosfstools
