[PATCH 1/3] configure.ac: Fix -Wimplicit-function-declaration for printf

[Sam James]

Clang 16 makes these errors fatal by default:
```
error: call to undeclared library function 'printf' with type 'int (const char 
*, ...)'; ISO C99 and later do not support implicit function declarations 
[-Werror,-Wimplicit-function-declaration]
```

printf(3) is provided by <stdio.h>, not <stdlib.h>.
