lib: array/hash - enable typof checks for more compilers
We have a HAVE_TYPEOF macro from autoconf, we may as well make use of it.

 /* Array is a buffer accessible using fixed size elements. As long as the
-   compiler provides typeof() function, the array provides type safety. If
+   compiler provides a typeof() operator, the array provides type safety. If
    a wrong type is tried to be added to the array, or if the array's contents
    are tried to be used using a wrong type, the compiler will give a warning.
