Need a "smoke test" before submits.

[milkypostman]

We need a set of packages which we should build that cover all the different dvcs systems for both unstable and stable builds.

Any suggestions? These should be packages which are both "popular" (so we don't break popular packages) and diverse (unique recipes, different dvcs, etc.).

• ivy: github, uses :files with both :defaults and :excludes. has 0.8.0 style tags
• evil: github, uses default files. large repo, 1.1.1 style tags
• m-buffer: github, uses :files with :defaults, v0.8.0 style tags

Lets get some more listed then I'll write a quick script we can put in the repo to run make on all these. It would help us to avoid where we accidentally break builds somehow. e.g.: #4693

It would also be nice if one could do something like make PACKAGE_BUILD=/work/in/progress/package-build.el .... That would make testing much easier.

@tarsius This isn't exactly the same, but: 4b770e4

This smoke test would probably belong with package-build, right?
