Fixed bug 3797 - configure check for float.h

Browse source 
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.
