Change minimum supported version for GCC to 4.8.1

[Anand Mazumdar <an...@mesosphere.io>]

I would like to propose that we bump our minimum supported version for gcc from 4.8.0 to 4.8.1. The main motivation behind this is that there are at least 2 outstanding reviews on RB that want to use ref-qualifiers <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2439.htm> introduced in GCC 4.8.1. The reviews in question are r41870 <https://reviews.apache.org/r/41870> and r41593 <https://reviews.apache.org/r/41593/diff/2?file=1173648#file1173648line58>. 

Also, our Getting Started document <http://mesos.apache.org/gettingstarted/> for Mesos already lists the minimum gcc version as > 4.8. Looking at the release timeline <https://gcc.gnu.org/gcc-4.8/> for GCC, it seems that 4.8.0/4.8.1 were released within a week of each other.

Does anyone have a strong opinion against this change ?
