aarch64: Fix tst-ifunc-arg-4 on clang-18

It issues:

../sysdeps/aarch64/tst-ifunc-arg-4.c:39:1: error: unused function 'resolver' [-Werror,-Wunused-function]
   39 | resolver (uint64_t arg0, const uint64_t arg1[])
      | ^~~~~~~~
1 error generated.

clang-19 and onwards do not trigger the warning.
