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
