I agree with Alan that it makes sense to add this trivial change as part of this PR, if it allows the current hsdis solution to continue working on mac/aarch64.

@a74nh I think Vladimir is referring to https://github.com/openjdk/jdk/pull/392. The hsdis "component" has been left behind for a long time, and there are several requests to add new backends, which require a modernized build of hsdis. This is undfortunately not a high-priority project, and has been postponed several times already. :(
