your point being ? I might as well tell you that I find the current
behavior of 'all*.config' just as broken wrt. to dependency

maybe you can come with a detailed description of your proposal's
behavior, including how to manage case like this, instead of just
throwing patch around ?

If I do:

# make CONFIG_WIRELESS_EXT=y allnoconfig

I expect either a success or an error, not a silent discard. And
*yes*, the problem already exists with "all*.config".
