Building a GCC cross compile tool chain for Linux ARM on OS X Mountain Lion

If you have a Beagleboard, Pandaboard, Raspberry Pi, or other ARM hardware running Linux, and you want to compile and debug C/C++ applications from your Windows or Linux desktop, it's relatively straightforward: download a pre-built tool chain from Mentor Graphics (formerly Code Sourcery). No such luck for OS X users. You have to build it yourself, and it's pretty painful. Hopefully, the info below will make it less painful for you. If you don't care to build the tools yourself, I posted the binaries on SourceForge.
