If accepting, don't forward to factory. Some more changes pending.
Plus we can see what breaks in the devel project first.

- update to version 1.62.0
* new library: fiber: framework for userland-threads/fibers
* new library: QVM: library for working with quaternions,
vectors and matrices of static size
* see http://www.boost.org/users/history/version_1_62_0.html
for complete changelog
- remove boost-fix_include_config.patch - upstreamed
- gcc_path.patch - fix GCC search paths (bnc#996917)
Boost assumes /usr/include/c++/x.y.z/ existence for GCC 4.x
onward while our version of GCC only has /usr/include/c++/x.y
for 4.x GCC and /usr/include/c++/x/ for 5.x onward.
- migrate to using %bcond_ instead of hardcoding macros
for different Boost features
- better way to limit max number of compilation units than
by reading /proc/meminfo and guesstimating.
