This is caused because the grub-efi recipe changes subtly between
qemux86 and genericx86: From bitbake -S printdiff:
  Variable GRUB_IMAGE value changed from 'grub-efi-bootia32.efi' to
'bootia32.efi'
  Variable GRUB_IMAGE_PREFIX value changed from '' to 'grub-efi-

However, the recipe arch is PACKAGE_ARCH, which is the same for both
machines. I _think_ this means that grub-ef should be change to be
MACHINE_ARCH instead, since its expected(?) that it will change based
on machine and not just PACKAGE_ARCH, but I'm not sure about that.

Alternatively (or maybe in addition to), perhaps do_deploy SPDX output
should always be written to a per-machine SPDX directory instead of
using SSTATE_ARCH? This has congruence with DEPLOY_DIR_IMAGE
containing MACHINE. I think this wouldn't actually work though because
DEPLOY_DIR_IMAGE is an sstate output directory (so I think it can
change without invalidating the task), where as SPDX is writing to
SSTATE_ARCH as an sstate input directory.
