Linux builds missing from nightly folders

[williamkapke]

The past few nightly folders only have Windows builds in them. Any idea where they went?
Example: https://nodejs.org/download/nightly/v7.0.0-nightly20160827c8619ea3c3/

My poor bash skills didn't account for this happening so node.green wasn't getting updated :(
