Benjamin Mahler resolved MESOS-1122.

commit ec74a1e3e3556615e68a8403cc4f62aa43f5153f
Author: Cody Maloney <cody@mesosphere.io>
Date:   Fri Oct 24 16:32:47 2014 -0500

    Add --enable-debug and --enable-optimize flag for controlling building debug and optimized verisons of mesos

    Reworks buiding mesos in a "debug" vs. a "release" configuration. By default, mesos is built in a developer-centric setup (No optimizations, minimal debug info), in order to maximize developer
 productivity

    None: '-O0 -g1'
    --enable-optimize == '-O2'
    --enable-debug == '-g'
    --enable-optimize --enable-debug == '-O2 -g'

    If a user / developer passes CXXFLAGS or CFLAGS manually, then they are not changed / touched at all. This is important so that Mesos is a good citizen when being built for various distributio
ns (As well as making it so specialized one-off groupings of flags are feasible to use).

    Adds two defines for accessing what mode things are being built in: 'DEBUG' and 'OPTIMIZE' which can be hooked into later to enable extra logging and the like. For release builds we may want t
o set 'NDEBUG' which removes assert()'s, but that is a seperate discussion.

> We currently only enable -O2 for g++ builds. It would be better to be consistent and also compile with optimizations for clang users.
