Add Makefile to compile test binaries

[dj-bauer]

I see, that many of the test parsers are put as a binary and source files. I suggest creating Makefiles for at least some of them so a script: build_tests.sh or similar could compile them all after cloning the repo. This could potentially massively shrink down the size of the repository to clone but also help with binary compatibility and ease of use. If you are interested in this feature, but don't want to implement this yourself, i would be willing to put some help in it :)
