Review request for mesos, James Peach, Michael Park, and Neil Conway.
Bugs: MESOS-6229
https://issues.apache.org/jira/browse/MESOS-6229
Repository: mesos
Description
-------
Add hardened flags for Mesos.
Take compile flag macro at 391cb680171d3889965b1ead43d3a326c913bc25.
The macro at 1a869696e4129279f7b99c3f9052717354b79a86 requires autoconf 2.64
which breaks on CentOS 6.

Testing
-------
Compared the benchmarks with and without the flags being used. Also did a
comparsion with the flags being used with and without optimizations and without
the flags being used with and without optimizations. Overall the performance
hit was very small with a 3-8% overhead (optimizations brings this down
slightly). Most benchmarks were about 5% (or less) slower.
Thanks,
Aaron Wood
