The new FAQ is very austere.  Once someone understands the process,
then presenting little more than a few lines of code as a reminder 
may (possibly) be adequate.  But if you are doing this for the first
time and are trying to understand what the process is, then there is 
little here to guide you.

I would suggest listing each of the configuration options which are
relevant and explain why you chose the values you did.  

Certainly newlib is a choice of runtime, but it isn't the only 
choice.  Building Glibc should be mentioned.  One of the failings of 
the current CrossGCC FAQ is that it only mentions Newlib.

Section 2.3 seems to be impossible -- it says you need to specify headers 
which are created by the next step.  The FAQ mentions --with-local-prefix
as being the location for standard header files, but it suggests that 
this is the location for TARGET headers.  It isn't; it is the location
for the host file headers, which should generally default to /usr/include.

When we do cross builds, we specify --includedir, --with-newlib, 
--disable-shared, --enable-cross.

My suggestion would be to try to correct the existing CrossGCC FAQ
rather than writing one from scratch.  You seem to fall into much 
of the same trap that I sometimes do:  only the final results are 
given, with none of the reason and rational.  Currently, the ratio
between text and code is about 1:1.  Much more description is needed.
