Subject: Start writing the kernel and add a linker script

Move the code unders [BITS 32] label to its own file to be loaded as a
kernel by the boot loader.

Add a linker script to link the bootloader and the kernel in a single
binary file.

Add a build script to make it easier to use the cross compiler

Update the Makefile to build everything and pack it into the os.bin
