First: sorry for inconvinience!

Seems to be an issue with the new build system - env tools do not see the 
kconfig defines when tqma6.h is preprocessed. I'm not sure what's the best
solution: if I include linux/kconfig.h at top of tqma6.h this build break 
is fixed. The canyonlands board  makes this, too. But I have the feeling 
that this should be better done at a central place, shouldn't it?
