CheckFunctionExists.c: avoid gcc warnings with -Wstrict-prototypes
Avoid warnings (and therefore build failures etc) if a user happens
to add -Wstrict-prototypes to CFLAGS.
| $ gcc --version
| gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4
|
| $ gcc -Wstrict-prototypes -Werror -DCHECK_FUNCTION_EXISTS=pthread_create -o foo.o -c Modules/CheckFunctionExists.c
| Modules/CheckFunctionExists.c:7:3: error: function declaration isn't a prototype [-Werror=strict-prototypes]
| CHECK_FUNCTION_EXISTS();
| ^
| cc1: all warnings being treated as errors
