The following instructions are valid for a default installation of Ubuntu 18.04.2 LTS preinstalled with gcc make perl

For JDK 12 the same works except I've only confirmed it with binutils-2.29 and binutils-2.32

I wanted to build hsdis for my Ubuntu system. Virtually all of the instructions out there are slightly wrong. As per the comment on this gist a recent change (bbd1da3f538f) to the HotSpot source to be compatible with binutils 2.29 broke all the prior instructions. So literally.. my contribution here is to publicly point this out and offer copy and pasta instructions to solve it.
