Same issue as the other error. Here a 64bit compiler was used to build a 32-bit kernel...
I've queued up a patch in for-next which should give a better error message if someone uses such a wrong combination: https://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git/commit/?h=for-next&id=b160628e9ebcdc85d0db9d7f423c26b3c7c179d0
