Somehow I missed this patch, and especially missed this
case when testing initial change.

And I think this is a wrong approach too.

This should be defined as qemu_helperdir variable instead of
CONFIG_QEMU_HELPERDIR, just like all other qemu_*dirs around,
and scripts/create_config will take care of it by expanding
the variable and providing CONFIG_QEMU_HELPERDIR #define.

Something like the attached.

Thanks,

This is indeed a better way to fix the issue. I have applied the
attached patch.
