Fixed bug 3797 - configure check for float.h
Ozkan Sezer Cmake checks for float.h, but configure does not: the attached patch adds float.h to checked headers in configury, and it adds the missing HAVE_FLOAT_H macro to SDL_config.h.cmake and SDL_config.h.in. In SDL_config_macosx.h and SDL_config_windows.h, defined HAVE_FLOAT_H as 1, where I know that it's true.
