"What is your strategy on cross compilation toolchains? Here we
explore a few options:
* DIY - requires you to manually start each step, unless you're
comfortable enough to script the process. As each step takes ages,
this can be a tedious job. However, it gives you full control and
insight into each step.
* crosstool [http://www.kegel.com/crosstool/] - a scripted version
of DIY + patches. Used to be my preferred tool, but hasn't been
updated since 2006. Limited to glibc.
