Needed: An easier way to build a subset of kernel packages

[Chuck Ebbert]

I was thinking about adding something like this to the .spec file
at the beginning:

%define allowup 1
%define allowsmp 1
%define allowpae 1
%define allowxen 1
%define allowdoc 1
%define allowdump 1
%define allowheaders 1
%define allowdebug 1

Then, after all the automatic enable/disable of various options is done,
turn off everything that's not allowed.

This would make it much easier to change what gets built.
