Lightshow works now Followed a tip from http://forum.osdev.org/viewtopic.php?f=1&t=20150 about moving the location of labels around, that made the linker error go away and it looks like that fixed the restarting problem. This commit also adds debugging flags to the build, and adds a debug make target with the right commands to run gdb under qemu, which I'll probably want to do in the future. 2015-10-22 22:24:51 -07:00			`extern rust_entry`
