Successfully builded kernel for LPC3250, it works on the board. But 
trouble with module-init-tools (configure try to use CC (set to arm 
compiler) as x86 compiler and fails due to "cannot run C compiled 
programs") still remains -- I temporarily solved it by explicitly 
setting CC=gcc in module-init-tools-cross_3.2.2.bb, though I don't think 
that it is good solution.

Maybe somebody more experienced could advise, how this trouble can be 
solved in the right way? I'm ready to give any needed logs.
