Yinghai, please get rid of the NUMAQ build option altogether and 
eliminate the subarch.

We should keep a compatibility CONFIG_X86_NUMAQ that selects 
X86_GENERICARCH, so that 'make oldconfig' on a NUMAQ config does the 
right thing - but it's not a subarch anymore nor anything 
user-configurable.

All that together would be a very nice simplification.
