No, please no...I am absolutely against allowing this.

It is OK for things like BR2_DL_DIR or BR2_DEFCONFIG, for which we have
explicit handling and does not "leak" into the target filesystem.

However, for configuration variables that affect the target filesystem,
I think we should not allow specifying them on the command line at all.
Or what, we could pass any-and-all options on the command line? Noooo...

Configuration variables that affect the content of the target filesystem
should all be confined to the .config file.

However, there is a remaining bug lurking around (see below).

Yes, maybe... I'll see to it.

Here, UTC is not quoted... I'll fix that.
