elf: Suppress unused function clang for __ifunc_resolver
The __ifunc_resolver macro expands to:
extern __typeof (__redirect_name) name __attribute__ ((ifunc ("iname_ifunc")));
static __typeof (__redirect_name) *name_ifunc (void) { [...] };
And although NAME_IFUNC is and alias for NAME, clang-18 still emits
an 'unused function 'name_ifunc' [-Werror,-Wunused-function]'
warning.
