It required a few changes beyond just the packages for libkrb5 - there was a missing library (ISL) required for the newer gcc, and a bug causing some of the files to attempt to install in /usr/local (missing `--prefix`). I'm not sure if this was exactly what you're looking for, but it's all on the latest commit on this branch for your review. I'm not sure how to test beyond the tests I've done locally.

As Mikael says, I think it would be better to break out any additional changes you made to the devkit makefile into a separate change, if we still want to go that route. I haven't looked into the ISL dependency much, but it looks like something we should add to the devkit for newer GCCs. For this change I was mostly interested in the extra libraries that would be needed in the sysroot. However, as @wangweij pointed out, if this could be handled with FFM instead of JNI, that would be even better and avoid all this hassle.

Happy to - will somebody need to create me an issue in the tracker so I can raise a PR?
