Compiling the compiler on OS X?

[chrisballinger]

It seems like the RPi tools repo only works on Linux machines. Any ideas how I could build the cross-compiler on OS X?

The problem I'm hitting is that the recipe for the rPi compiler in crosstool-ng wants gdb-7.8 and the sources it has listed no longer host it.

The steps are pretty simple:

1. Install crosstool-ng (and other dependencies)
2. Create two disk images, one to hold the source and the other to hold the output (crosstool requires a case-sensitive filesystem)
3. Mount those images in the places where crosstool-ng expects them
4. Configure ct-ng in the output filesytem - ct-ng armv6-rpi-linux-gnueabi
5. ct-ng build to create the crosscompiler
