Adopt approach from JuliaComputing/static-julia?

[tkoolen]

@ViralBShah recently posted a different approach to building binaries from Julia code on Discourse. See this comment for some differences. Should the functionality of https://github.com/JuliaComputing/static-julia (which is currently more of a tech demo than a full-fledged utility) be incorporated into BuildExecutable?

It would certainly be a good idea to take that prototype and make it part of this package, and also hopefully fix some of the issues (like names of files, running in the same directory, etc.).

I am hoping this can all become easy to use and eventually ship as juliac in the Base Julia distribution.
