Compilation error on aarch64

[gyscos]

While trying to compile paru for aarch64, it seems compilation fails here:

This seems to be using the latest commit (306342e).

$ rustc --version
rustc 1.76.0 (07dca489a 2024-02-04)

And indeed, alpm-sys defines:

alpm.rs/alpm-sys/src/ffi.rs

Lines 3322 to 3329 in adad998

	pub type alpm_cb_log = ::std::option::Option<
	unsafe extern "C" fn(
	ctx: *mut ::std::os::raw::c_void,
	level: alpm_loglevel_t,
	fmt: *const ::std::os::raw::c_char,
	args: *mut __va_list_tag,
	),
	>;

Regardless of architecture, while

alpm.rs/alpm/src/cb.rs

Lines 13 to 16 in adad998

	#[cfg(not(any(target_arch = "arm", target_arch = "aarch64")))]
	pub type VaList = *mut __va_list_tag;
	#[cfg(any(target_arch = "arm", target_arch = "aarch64"))]
	pub type VaList = va_list;

defines it differently on arm and aarch64.
