Efforts to document LO build system

[David Ostrovsky]

Hi,

FYI: i just added new wiki page:
https://wiki.documentfoundation.org/Development/Build_System

I am going to add there more inforamtion (and some diagrams).
Many thanks to David Tardon for help!

The target is: after reading this page, every one should not only
understand LO build process itself,
but be able to explain it to his wife (or husband)
;-)

To achieve that, your help is highly appreciated.

Regards
David
