Return EXIT_UNSUPPORTED if __builtin_mul_overflow unavailable 

Since GCC 4.9 doesn't support __builtin_mul_overflow:

tst-fd_to_filename.c: In function ‘check_ranges’:
tst-fd_to_filename.c:51:3: error: implicit declaration of function ‘__builtin_mul_overflow’ [-Werror=implicit-function-declaration]
   while (!__builtin_mul_overflow (power, base, &power));
   ^
cc1: all warnings being treated as errors

return EXIT_UNSUPPORTED for GCC 4.9 or older.
