H.J. Lu 31c47126f4 string: Suppress Clang warnings on tester.c
Add a configure check for -Wno-fortify-source to suppress Clang warnings
on string/tester.c, like:

tester.c:385:10: error: 'strncat' size argument is too large; destination buffer has size 50, but size argument is 99 [-Werror,-Wfortify-source]
  385 |   check (strncat (one, "lmn", 99) == one, 1);   /* Returned value. */
