Test all commits during rebase

Before making a pull request, it is useful to make sure that compile is successful and tests are passing for each commit in the branch. We can do that automatically using -x parameter.

For example:

git rebase -i -x make

will perform the interactive rebase and stop after each commit to execute make. In case make fails, git will stop to give you an opportunity to fix the issues and amend the commit before proceeding with picking the next one.
