Early work on Synergy.

* Make Haiku a recognized platform.
* Build fails early for an unknown reason (compiler prints some warnings
and stops)
* Not sure wether this can be built with gcc4 (secondary compiler), as
it would need to work as an input_server add-on...
* Synergy homepage does advertise gcc2.95.3 as the minimal required
version, but that may be out of date.
