mawk in Ubuntu 20.04

Well that explains a lot. For years at work I ran into a strange issue in the build system where when new people started they would get mysterious segfaults. Install gawk and the problem went away. I would have filed a bug but it was so deep inside configure with several extra layers of indirection that I didn't bother. That project has since been retired (thank god).

I personally found awk to be just a little confusing past the simple cases and simply replacing awk with perl -lne made it do what I want. I guess I just knew perl better than awk.
