[Libreoffice] --enable-werror

I think I wasn't clear.

I started doing things in LO when things were a lot harder than they 
are now. I'm glad for all the community members who have been putting 
order in this chaos. That experience lead me to believe that the policy 
should be "make it easy for the n00b".

When I tried using this flag, I ended up not being able to _build_ at 
all. And that wasn't even due to my own mistake, only some  module I 
know nothing at all is breaking the build. The best advice I got on IRC 
was to disable the flag!
And that was 1-2 months back, max.

My point is that building for a n00b should be very simple. And we can 
put that flag in the module-specific make file with the right switch. 
make -r is building, make -sr is building and running the unit testing, 
make -er would be building with all the restrictive flags.
Something like that...

What do you think?
