Force --std=gnu89 for clang

Desktop / LibreOffice - Andrzej Hunt [collabora.com] - 26 September 2014 03:11 UTC

clang builds with a more modern standard by default

On Linux gcc builds with gnu89 by default. On Windows MSVC only supports C90. Hence it makes sense to force gnu89 for clang to catch potential gnu89/C90 incompatibilities locally.

(C90 and gnu89 appear to be quite close, however using C90 with clang results in warnings and errors to do with comments on lines with code (-Wcomment), and also the lack of inline (instead you would use __inline -- this is #define'd in for Windows only).)
