Hi, I tried to build ring on s390x platform but got error:

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', build.rs:364:34

From build.xs, line 364:

    let (_, _, perlasm_format) = ASM_TARGETS
        .iter()
        .find(|entry| {
            let &(entry_arch, entry_os, _) = *entry;
            entry_arch == &target.arch && is_none_or_equals(entry_os, &target.os)
        })
        .unwrap();

I searched ASM_TARGETS from build.xs:

const ASM_TARGETS: &[(&str, Option<&str>, &str)] = &[
    ("x86_64", Some("ios"), "macosx"),
    ("x86_64", Some("macos"), "macosx"),
    ("x86_64", Some(WINDOWS), "nasm"),
    ("x86_64", None, "elf"),
    ("aarch64", Some("ios"), "ios64"),
    ("aarch64", None, "linux64"),
    ("x86", Some(WINDOWS), "win32n"),
    ("x86", Some("ios"), "macosx"),
    ("x86", None, "elf"),
    ("arm", Some("ios"), "ios32"),
    ("arm", None, "linux32"),
];

It seems the error is due to no s390x support?

My question are:

  1. Does ring support s390x?
  2. If it does, how should I build it?
  3. If it doesn't, will it support s390x in the future? And if possible, at what time?

Thanks
