In order to build reproducible firmware images, Heads builds a specific
version of gcc and uses it to compile the Linux kernel and various tools
that go into the initrd. Unfortunately this means the first step is a
little slow... After cloning the tree, cd into it and run `./bootstrap`
to download and build binutils, gcc and all of their dependencies into
`./crossgcc/`.
