[Buildroot] Architecture build statistics

[Chris Zankel <chris@zankel.net>]

Hi Thomas,

Great statistics. Xtensa definitely needs some work here ;-)

I looked into the failures a while ago and started to create patches. 
However, one major issue was lacking NPTL support in uClibc. We are 
currently working on it and are getting close to support it. This 
already should push the pct columns higher :-)

Thanks,
-Chris
