Boost Makefile Update to Version 1.59

This commit updates Boost to version 1.59, released in the 13th of August of 2015 [1].
  - The new version adds two new template libraries, Convert [2] and CoRoutine2 [3].
  - [Warning]-> CoRoutine2 library absolutly requires a C++14 compiler.
  - patch 001-mips-options-fix.patch was removed, since it is already incorporated upstream.

[2] - http://www.boost.org/libs/convert/
[3] - http://www.boost.org/libs/coroutine2/
