Merge linker scripts in bootrom to have a single linker script for the bootloader...

1 # This new makefile replaces the previous Makefile/Makefile.linux
2 # with as much common code for both environments as possible.
3 # Following is a short OS detection to set up variables, all the
4 # remaining Makefile should be portable and only depend on these
5 # variables
