It looks like to be an issue with the .config. I have a working linux if
I disable most the CONFIG_MACH_* and CONFIG_ARCH_*.

Touching those CONFIGs also modify CONFIG_DEBUG_LL_INCLUDE.

The current value of CONFIG_DEBUG_LL_INCLUDE looks wrong to me but I
still need to figure out if it's really an issue or not.
