Makefile: generate util/build_version.cc from .in file (#1384)

Browse Source 
* util/build_verion.cc.in: add this file, so cmake and make can share the
  template file for generating util/build_version.cc.
* CMakeLists.txt: also, cmake v2.8.11 does not support file(GENERATE ...),
  so we are using configure_file() for creating build_version.cc.
* Makefile: use util/build_verion.cc.in for creating build_version.cc.
