There are other cases where this is not working.
If there are int or hex symbols without a default value, "allmodconfig",
"allyesconfig", "allnoconfig", and "randconfig" fill in empty string values,
causing a subsequent build (which does oldconfig) to wait for user input.

This is easy to reproduce:
    make ARCH=h8300 allmodconfig
    make ARCH=h8300 oldconfig

Should kconfig generate default values for these cases?
Should all int/hex symbols provide default values? If yes, I think
kconfig should
complain about missing defaults.
