I'm both sympathetic and frustrated by this as well.

One consequence of not having documentation which is correct (or even
close) is that we don't find bugs in the build process.  It makes it
difficult to tell whether a problem building a cross-compiler is
(a) user error, (b) errors in the documentation, (c) unclear interactions
between the configure options, (d) interactions or incompatibilities between
components, or (e) errors in the implementation.

I'd like to see the CrossGCC FAQ actually be a list of Questions and
Answers, not a script for building a cross-compiler with one specific
set of options for one particular purpose.  IMO, we (the proverbial we,
that is) could likely mine the GCC mailing list to find the common
questions and the common answers.

As Daniel said, lack of time/experience/motivation is a factor.  I'm
reluctant to say that I'll take a stab at a FAQ, given that I have limited
time and every time I look at GCC configuration I feel that I'm being
sucked into a tar pit.  :-)
