Added a case to build_config.h to cover compiling for Linux with 16-bit wchars  (alongside the existing cases for Windows with 16-bit wchars and Linux with  32-bit wchars) so that it becomes possible to compile and link the Chromium  base together with third-party libraries that require short wchars.
