Makefile ports tweaks cleanup etc

Was bored, so I decided to attempt to fix up the Makefile so the old console ports (Dreamcast, Xbox, PSP, PS3, GP2X, Wii) and Windows CE have a chance of being compiled again, if anyone wanted to try. Basically I just made them refer to the SDL 1.2 interface files instead of the SDL 2.0 files.

I have no hope of compiling any of these myself though, and many of them may not even work anymore anyway shrugs.

EDIT: This branch also removes all code for the ports listed above from the SDL 2.0 interface code, since they no longer use it. Additionally, I readded all the missing objs and bin subfolders from whenever we moved to Git, some of which concerned these ports (some not).
