Test GC-Linux

[ogamespec]

Run the 2004 GC-Linux builds and see what happens.

With the latest improvements by MMU and Cache Linux starts, but
freezes in some kind of polling loop.

It is necessary to improve the GekkoCore emulation and understand further what it wants.

After fixing the mtsrin and mfsrin instructions, it sets up the memory model and starts up, but still doesn't display anything on the screen. (spinning in cycles)

Found some GC-Linux with a memory map!

Detached this Issue from any milestone because GC-Linux is proving to be a tough nut to crack and won't let me do releases lol.

Current status: falls into panic with text like "Deleted Idle process". When the HLE subsystem will be redesigned I will add panic outputs to the debugger and then we will see more details (now the text of the message can be seen only by the r3 register and memory dump).
