Building

##On Debian/Ubuntu:

1. Before you start, install libgmp-dev, libmpfr-dev, libmpc-dev, libncurses-dev and texinfo.

2. Then use the Makefile from here: https://github.com/caltry/cross-tools

3. Running 'make' should download and install everything for you in $PWD/local-prefix. Add local-prefix/bin to your path and you should be able to build XINU.
