Updates the makefiles to set up for compilation and building for *BSD. This is a cleaned up diff towards the existing BSD port from the battleblow/jdk repository.
Some parts have been held back for later PRs, mainly because I expect them to require more thorough review. (Some is also probably outdated, and we'll go through those first.) This work is sponsored by The FreeBSD Foundation.
