Ticket #2115 - another note about unpacking and changing directories

[Bruce Dubbs]

http://wiki.linuxfromscratch.org/lfs/ticket/2115

I am starting to address the subject ticket.  I propose to follow Chris' 
suggestion and move the 'Toolchain Technical Notes' section to the appendix 
between Acknowledgments and Dependencies.  I will then change the Introduction 
to refer to 'Toolchain Technical Notes' and tidy up any other wording changes 
that are needed.

Any objections?
