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,

Subject: [PATCH] fix CONFIG_QEMU_HELPERDIR generation again

commit 38f419f35225 fixed a breakage with CONFIG_QEMU_HELPERDIR
which has been introduced by 8bf188aa18ef7a8.  But while techinically
that fix has been correct, all other similar variables are handled
differently.  Make it consistent, and let scripts/create_config
expand and capitalize the variable properly like for all other
qemu_*dir variables.
