Linker fix for initialized global variables 

I found that in some cases, initialized global variables don't work with user libraries, so a little change to the linker that I use, taken from the demo file, seems to solve the problem . I think that make more sense to put the global variables in sram and initial values in the main_ram, similar to the bios linker.
