Fun bug: if I inlined mem.spanZ(mcpu_oz) into the CrossTarget.parse expression I got:

broken LLVM module found: Call parameter type does not match function signature!
  %67 = getelementptr inbounds %std.zig.cross_target.ParseOptions, %std.zig.cross_target.ParseOptions* %10, i32 0, i32 1, !dbg !20878
 %"?[:0]const u8"*  call fastcc void @std.mem.spanZ.176(%"?[]const u8"* sret %67, i8* %68), !dbg !20880

This is a bug in the Zig compiler.
