Al,
I happen to be learning how to cross-compile on Debian right now, so i can testify that building the cross toolchain 'The Debian Way' is even easier than you describe ;).

The package toolchain-source (together with dpkg-cross) makes the process even more automatic. Detailed instructions are at: http://people.debian.org/~debacle/cross.html
The short story is: # apt-get toolchain-source dpkg-cross autoconf2.13 fakeroot # tpkg-install-libc <terget>-linux # grabs, converts and install the headers $ tpkg-make <target>-linux # no need to patch anything $ cd binutils... $ debuild -us -uc # no magic env variables # dpkg -i ../binutils...deb $ cd ../gcc... $ debuild -us -uc # dpkg -i ../gcc...deb
If I'm not mistaken, that's all.

Sadly right! guess which platform I needed to cross compile :-/
