with the last upload (and the switch to llvm 3.8) this list is down to
amd64, i386 :-(
and powerpcspe was probably only "succcessful" due to using
DEB_BUILD_OPTIONS=nocheck

depends a bit on the role of pyopencl - if it is similar to libopencl1,
the "any" might do. Otherwise it would be nice to have tests run at
build time ... and since that wont work in many cases due to hardware
requirements, before adding a new architecture pyopencl should have been
veryfied to work correctly against the available (proprietary) ICDs.
