9c4d057e3d Don't implement lang items on testing 
The `std` library is imported on testing. It already implements all lang items.

5db8977495 Rename main to rust_main to support testing 
On testing, `std` is imported, which defines an own `main` function. Thus `cargo test` fails if there alread exists one non-mangled main.

fcf69dcc53 Remove unused sections to avoid float issues 
Avoids a linker error for `fmod` and `fmodf`. These functions are refenced in libcore. The KEEP ensures that the Multiboot section isn't removed.

262e64f184 Add a Makefile 
It provides `make` (builds the kernel), `make iso` (builds kernel+ISO), and `make run` (builds kernel+ISO and starts qemu). All assembly files from the arch subdirectories are compiled and linked. It also provides basic multi-architecture support through e.g. `make arch=mips iso`.
