Yes, this should be a working workaround. It basically disables
parsing of the problematic boost headers by automoc by defining their
include guards.

I've already implemented this workaround in fatrat[1] and
luxrender[2]. The only difference between how I used this workaround
and how it's used in fedora is that I'm explicitly setting these
parameters while compiling something using automoc, while the fedora
makes them default for every automoc run (so they don't need to be set
explicitly).
