radare2 [1] is a portable tool and should work everywhere, like you expect to do the same from GDB, for example.

There is a radare2 package in pkgsrc, I presume it works.

We run our tests on different platforms, for example the native debugging and emulation, where platform differences can play the role. And we run them on every commit, to prevent regressions.

You still haven't explained what you want to do and why I (as a NetBSD developer) should be interested.

Sourcehut makes it easy to run CI for a lot of platforms at once. Helping it support netbsd helps developers target netbsd easily.

For example, the emulation and debugger depends on the platform, so running debugging tests on CI helps us to improve and refactor corresponding code without much hassle.
