Could this pipe be part of a french drain or something else related to a sump?
It actually isn't that bad of a place.  


Most basement bathrooms I do end up being in a corner.  
Builder planning on actual drain location is basically useless because they can't get in your head on what you will want in 5 years.
Remember that what you are currently seeing will be covered.  
The corner location allows you to easily connect your sink drain without busting up more concrete for that.  So you will bust up the concrete around this and connect your toilet and shower to a point where you have an acceptable pitch for each.  Toilet will need to be relatively close and shower can be further away.  Given that it is in the corner I can throw an adapter on the top of this and run the venting and the drain from sink through the walls.  If this was in the middle of the room you would have an extra line that you would have to connect below grade for sure.  
Given this configuration and a "normalish" bathroom you could bust up concrete with just sledge hammer and have toilet, shower, and sink lines completed in a couple hours.  After it gets inspected you could have this concreted the same day if you can line up your inspector right and if he trusts that you will have it completed (you would have cut the top off and framed beforehand if you want it done quicker).


So really if I am doing a bathroom this is a great place.

Edit:  Since the OP added that they are installing a french drain on the perimeter my advice would to leave this in tact and work around it.  There is no reason this should really affect a french drain system.
