From 5ceda644200c8c84b9c1ea66f2ee677d374c34cb Mon Sep 17 00:00:00 2001
From: David P <megver83@parabola.nu>

Subject: [PATCH] Add offline files, and a toolchain option in Makefile

The *.offline files are so if you want to build offline, you just have to
pass toolchains= unset, or toolchains=1 for downloading them (which is the
default). Read the INSTALL file for more.
