git config issues

[Robin Getz]

When doing something like:

analog@phaser:/usr/local/src/libiio $ sudo git checkout master
Previous HEAD position was fb64aca examples/cmake: Fix iio-monitor dependency checks
Switched to branch 'master'
Your branch is behind 'origin/master' by 58 commits, and can be fast-forwarded.
  (use "git pull" to update your local branch)
analog@phaser:/usr/local/src/libiio $ sudo git pull
hint: Pulling without specifying how to reconcile divergent branches is
hint: discouraged. You can squelch this message by running one of the following
hint: commands sometime before your next pull:
hint: 
hint:   git config pull.rebase false  # merge (the default strategy)
hint:   git config pull.rebase true   # rebase
hint:   git config pull.ff only       # fast-forward only
hint: 
hint: You can replace "git config" with "git config --global" to set a default
hint: preference for all repositories. You can also pass --rebase, --no-rebase,
hint: or --ff-only on the command line to override the configured default per
hint: invocation.

doing a simple (once as root, once as a normal user):

analog@phaser:/usr/local/src/libiio $ sudo git config --global pull.rebase false
analog@phaser:/usr/local/src/libiio $ git config --global pull.rebase false

will get rid of the annoying message.
