Fix compile error in configure script

Building with GCC 14 fails at the configure step with:

./configure: error: libatomic_ops library was not found.

The error is not caused by a missing library, but by an unrelated
"incompatible pointer type" error in the test program:

...
checking for atomic_ops library
objs/autotest.c: In function 'main':
objs/autotest.c:9:48: error: passing argument 1 of 'AO_compare_and_swap' from incompatible pointer type [-Wincompatible-pointer-types]

Fix the error by using the correct pointer types.
