[Fontconfig] C++11 requires a space between literal and identifier

http://cgit.freedesktop.org/fontconfig/tree/fontconfig/fontconfig.h#n115

leads to:

usr/local/include/fontconfig/fontconfig.h:116:39: error: invalid
suffix on literal; C++11 requires a space between literal and
identifier [-Wreserved-user-defined-lit
#define FC_CACHE_SUFFIX             ".cache-"FC_CACHE_VERSION
                                            ^

/usr/local/include/fontconfig/fontconfig.h:118:47: error: invalid
suffix on literal; C++11 requires a space between literal and
identifier [-Wreserved-user-defined-lit
#define FC_USER_CACHE_FILE          ".fonts.cache-"FC_CACHE_VERSION
                                                  ^
this could be fixed by simply adding a space.
