Following the Bootlin toolchain bump to 2023.11-1 [1], the
TestGrubX8664EFI failed 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
Actually this error can be reproduced by installing other packages like
"file" because the qemu emulation doesn't provide all assembler
instruction emulation required by x86-64-core-i7 target used by
TestGrubX8664EFI.
A similar issue has been fixed in toolchain-builder by adding Nehalem
cpu emulation on the qemu command line [2].

Thanks for improving the commit log with additional important informations about
the root cause of the issue.
I really appreciate and I'll try to do even better next time :)
Best regards,
Romain
