I guess the OR is perfectly fine then. For whatever reason make
oldnoconfig fails, we'll fall back to the old behavior.

I think you got it wrong:
 - I am already using an updated kconfig (I even backported it on the
older kernel version)
 - make oldnoconfig is NOT setting things to NO but to the default value
of the unspecified options (exactly what we need). The choice of the
name was not wise and It has been renamed olddefconfig since 3.7
