FEATURES="-strict" emerge  mpich2 # works on my Raspberry Pi

The mpich2 ebuild has a dependency for sys-apps/hwloc, this in turn pulls in numactl which are not supported and won't build on my ARM system (Raspberry Pi). 

If I removed the sys-apps/hwloc dependency mpich2 builds fine and from my tests works perfectly again ARM system (Raspberry Pi).

Can this (sys-apps/hwloc) dependency be removed for ARM and the keyword for mpich2 changed to ~ARM?

Attached my edited ebuild and patch.

@arm:  How would you guys like to handle this?  mpich2 does bundle sys-apps/hwloc which is probably why things are working for Laurence when the DEPEND is removed.

=sys-apps/hwloc-1.10.0-r1 is keyworded on arm.
