Commit r301144
http://llvm.org/viewvc/llvm-project?view=revision&revision=301144 causes
LibreOffice Unit tests to fail during the build. 

Steps to reproduce:
1. $ git clone git://anongit.freedesktop.org/libreoffice/core
2. $ apt-get build-dep libreoffice ( also lo_usefull Shell Script if missing
dep)
3. Remove ccache if it's installed ( ccache generates warning w/ clang)
4. create file autogen.input with CC=clang and CXX=clang++
5 ./autogen.sh && make 

r301143 and earlier:
Build completes without error
