I'll be adapting the instructions [at the OSDev wiki](http://wiki.osdev.org/GCC_Cross-Compiler).
Using a package manager
-----------------------
On some systems, the cross-compiler can be installed by a package manager.
On Linux, use your package manager to install `gcc`. On a Mac, [install Homebrew](http://brew.sh/)
if you didn't do it on lesson 00, and then `brew install i386-elf-gcc`
If this doesn't work, you may need to build the cross-compiler yourself.
Required packages
-----------------
First, install the required packages. On linux, use your package distribution. On a Mac, [install brew](http://brew.sh/) if
you didn't do it on lesson 00, and get those packages with `brew install`
