Add support for Makefile as build script and make as build tool

[behnazh-w]

Makefile is often used as a generic build tool. In fact, Macaron itself uses Makefile to generate artifacts. We already have support for a number of build tools.

To support Makefile

• we need to add a parser for Makefile to extract shell commands, similar to our bashparser.
• add a new module for make similar to other build tools.

I poked around a little, and here are a few references. First off, It would be tricky to write a grammar for make, since the grammar is extremely context-dependent. (thread, similar questions here or especially here).

Having said that, I found the following attempts to come up with a Makefile grammar:

• https://github.com/Icraus/MakefileGrammar
• https://github.com/grammarjs/makefile (requires other repos from the same org)

It might also make sense to explore existing syntax highlighters like Pygments which support at least Makefile lexers.

@behnazh-w given a Makefile, it looks like you’re interested in extracting the Recipes from it?

Yes exactly. Our ultimate goal is to find shell commands that invoke build tools. For now we can limit the Recipes to bash scripts.
