it's pretty easy to build cross compilers under Debian. Below a quoted
mail from one of the Debian Maintainers describing how you can do this.
If you want to use the more generic approach you'll find plenty of
cross-gcc-HOWTOs on the web.

Is it? I tried that toolchain, and I'm failing with building of the
libc. It downloads something 10 MB from UK server, and then errors saying
some dependency db1-arm-something.blabla cannot be fount.
you won't need a libc for an embedded ARM running a firmware - you won't
have any operating system, no i/o -- nothing the glibc is relying on.
You only have to build binutils and gcc-core.
