[Libreoffice] [GSoC] link-time optimization

[Jan Hubicka]

Hi,
thanks to Michael I made some progress on building Libreoffice on my setup.
The problem of configury was that -flto was not passed at linktime and  
also -fuse-linker-plugin was missing.

My build currently dies on svx on GCC bug. I've created tracking PR
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50394
I will continue fixing issues until I link svx and lets see what we  
could do next.

There are however quite few errors reported by g++ 4.7.  It would  
really rock if someone tried to build libreoffice with mainline GCC  
and no lto and fixed those.
Also -fpermissive is needed.
