commit b160628e9e upstream.
It happens quite often that people use the wrong compiler to build the
kernel:
make ARCH=parisc -> builds the 32-bit kernel
make ARCH=parisc64 -> builds the 64-bit kernel
This patch adds a sanity check which errors out with an instruction how
use the correct ARCH= option.
