[Libreoffice] GnuMake

Ok so I've pushed a feature/gnumake2 branch.

It contain about half of the gnumake2 CWS plus few adjustment due to
the fact that things have changed in our trees.

I pushed at this point because:

1/  the regular build still function fully using the old method. and
the modules "framework ooo sfx2 svl svtools sw toolkit tools xmloff"
build successfully with the new gnumake system.

2/ I ran into a stretch of patches that rely on CWS sb139  being
merged ( this implement a fix to
http://qa.openoffice.org/issues/show_bug.cgi?id=113189 'passive
registration of UNO components' )
that CWS had been merged into DEV300_m89. It is 15 or so commits, some
of them massive( one is a 1.5MB patch) and is addressing a problem I
know nothing about (yeah, I know... one day I need to find a way to
grasp that UNO thing :-) ).

Furthermore that also create a new module (xmlreader) which need to be
assigned a git repository

All that lead me to conclude that it would be wiser to wait and see
what we do with m89 (kendy?), wait for it to be merged/cherry picked
and then resume merging the rest of gnumake2

3/ I've done things on Linux so far. I'll be able to pull on MacOS and
iron the problem there.... As usual Windows will have to be left as an
exercise to the reader.
