Instead of saving the prefilterings parallel temp results into temp files, we channel everything to STDOUT and merge with pipe

Added power support for the travis.yml file with ppc64le. This is part of the Ubuntu distribution for ppc64le.

Clean empty .git.ignore tmp file as well and use something non-empty when checking has not been enabled

* Add functionality to respect .gitignore
