The difference is, I am building gcc 7.2, but other versions of gcc would do. My problem is at the stage of building the full gcc cross-compiler the build stops

Thanks, I should add a couple of things, I couldn't build the newlib 2.5 sources, I hit the same error as described here:

https://sourceware.org/ml/newlib/2016/msg01117.html

I instead used the newlib 2.3 sources.

The other thing is that my test with gcc 6.2 was actually done using crosstool-ng

http://crosstool-ng.github.io/

Which automates the cross-build. I don't know if this uses the three step build method, it may not.
