No. Use a .gitignore instead of .gitkeep. Instead of checking in build/.gitkeep, check in build/.gitignore.
I don't know that I like this approach. It certainly works, but it's not specifically what (people expect) a .gitignore file to be used for. That confusion isn't good: https://thecodelesscode.com/case/222 and https://thecodelesscode.com/case/223
