This packaging directory can be used to build few versions of cross gcc:

- 4.4
- 4.5
- 4.6

Steps requires to switch between them are:

$ cp debian/changelog-VER debian/changelog
$ debian/rules control

For now cross toolchains for two architectures are available:

- armel
- armhf

Steps requires to switch between them are:

$ vi debian/changelog
> change first entry to "gcc-VER-ARCH-cross"
$ debian/rules control

And then rebuild package.
