well... powertop cross compiles like all other userland... (override 
CC). I think that's both obvious enough and standardized to the 
extreme that adding something only the kernel does isn't all that 
useful... it just makes things more complex for people who crossbuild.

So I think I'll skip this one; I appreciate the contribution though!
