So what's changed? It looks like, for whatever reason, make installmandocs always ends up rerunning mandocs -- there's now a 'GEN Documentation Docbook//v4l2.xml' printed, and that extra mandocs invocation is where the problematic second invocation of find is coming from. I won't pretend to understand the Makefile flow to guess at why that's happening, but obviously 'make mandocs; make installmandocs' shouldn't need to regenerate things already generated.
