Sorry for misunderstanding.
Indeed, make *config which use 'conf' (e.g. oldconfig, defconfig...)
raise error.
And only xconfig and gconfig don't write the configuration without
error.

However, make *config using 'conf' hasn't function of 'Save as'.
In other words, if you don't set the write permission to the directory,
you would lose changes of the configuration.
I think that it is necessary to check permission at all so that kconfig
warn of the possibility of losing changes.

Thanks
