Apparently Khem had this working prior to the update to valgrind v3.11

  http://lists.openembedded.org/pipermail/openembedded-core/2015-December/114340.html

Looking at the code I don't see any easy way to build for armv5
though. Maybe it's hackable, but the result probably wouldn't be
suitable for oe-core.

Probably the best solution is to restore the blacklisting of armv6 and
below. I'll send a patch.
