I should think so. Do make sure you build a debian-style toolchain - i.e.
not one that installs to /usr/local/ It would be best to build from the
latest debian binutils and gcc packages so that we can keep in sync with the
Debian mainstream. If you wrote a script that would automagically produce
x86->arm, powerpc and m68k C and C++ cross-compilers and binutils, that
would be great.
The process is all nicely documented in the gcc/docs/cross-compile file.
This is the sort of thing that machine offered to set up would be handy for.
Any progress on that?

there are also a couple of good ones at http://www.arm.linux.org.uk/

Yes 3.2 was not good (on arm at least). 3.3 is much better and even mostly
works :-)
