Patch for xconfig

[Pete Zaitcev]

My customers complain that using certain canned configurations
xconfig does not work (naturally, it works with defconfig).
A problem that I am trying to fix is that it can refuse to
quit with something like "Variable CONSTANT_M does not exist".
The necessary "global" is indeed missing.

Can someone knowledgeable (like Chastain) have a look at
the attached patch?

Thanks,
