[TIMOB-12169] Create build log with compilation

Resolves https://jira.appcelerator.org/browse/TIMOB-12169
After talking this over with the team, I think we need to just nuke everything in the build folder. We can trim this whole chunk of code (including the code before the `else` to:

~~~
var file = path.join(buildDir, dir);
cli.fireHook('clean.' + dir + '.pre', function () {
	logger.debug(__('Deleting %s', file.cyan));
	if (fs.lstatSync(file).isDirectory()) {
		wrench.rmdirSyncRecursive(file);
	} else {
		fs.unlinkSync(file);
	}
	cli.fireHook('clean.' + dir + '.post', function () {
		next();
	});
});
~~~
