make test command fails

[dguo]

I wasn't able to run the tests out of the box. I'm running Node v9.7.1 and npm v5.7.1. I did npm install and make test and got this:

make: node_modules/make-lint//node_modules/.bin/eslint: Command not found
make: *** [node_modules/make-lint/index.mk:8: lint] Error 127

1. It looks like there is an extraneous forward slash after make-lint in the path.
2. There is no node_modules subdirectory within node_modules/make-lint on my machine. I think the Makefile was written before npm v3. Since then, npm tries to flatten the dependency tree.
