Add support for Linux

[intrepid-developer]

Is there any chance you can port this to support Linux as well please. Since this has been introduced into the monodevelop repository we've been unable to build any 8.* branches on Linux. You're alienating the entire Linux community by breaking the open-source monodevelop IDE and preventing us from using it. We're stuck on the older 7.* versions which means we're not able to fully utilise the advancements being made in the dotnet world, things like Balzor just don't work properly. Please can you show your supposed love of Linux and actually support monodevelop properly on Linux and Mac. There have been open tickets in the monodevelop repository for over 6 months trying to get this resolved.
