that is confusing

they are just trying to make it so you can control who what and where with a very complex settup
--prefix=/opt/hide/the/compiler and still get the behavior you want
to tell you the truth the ins and outs of tool chains and trying to controll what symbols get into what compile are complex
and often gcc itself seems to have forgotten to read it's own confusing manual.
I know this isn't what you asked but i say you have to follow a build on this one someone has already tested out the actual results or the whole thing will get all fubar on you.

this is a great resource for cross compile toolchains

As I read it, it means that if "with-sysroot" is used or has been set (someone correct me if I'm wrong but I believe that its possible to set some of these options as system variables and/or once an option has been set then the values are remembered) then using "-with-build-sysroot" will cause "with-sysroot" to be ignored in-favor of "-with-build-sysroot"

Cross compile toolchains :

Crosstool-ng : Recommended, and the only one
that is maintained. Last update = 31 July 2011.

Learning how to build tool chains : Build LFS, move on to CLFS,
like said in post # 2.

But the easy way is still 'crosstool-ng'. Can take weeks to build your own.
