Crosstool-NG aims at making it easy to build cross-toolchains for many architectures, using the traditional FLOSS components (gcc, binutils, glibc, uClibc, etc.) and offering a lot of configuration options. While the process of building a toolchain can look like black magic, crosstool-NG automates that process with a set of scripts and patches in an easy-to-follow flow, so the user understands what is happening and why it is happening.
