So far we've kept the number of 'user serviceable' build options very 
small, preferring to select optional things at run time, and specify 
non-optional things by hardcoding in asm/config.h.
What is it that PPC requires in addition to this? If it's the ability 
to more easlly have those config.h hardcodings affect what files get 
built, then maybe we can pull out those hardcoded CONFIG_ items into a 
per-arch text file that gets processed into a header file and into a 
Makefile include.
Not so sure about doing that for user-specifiable items, since there 
are only a small handful. Modifying root Config.mk would be the right 
place to put user-specific defaults for those I think.
