[Trisquel-users] Clang error. How to set libc++ as default for Clang?

[stas . mihaylenko]

I need to compile Certificate Transparency. I stuck at missing "algorithm"  
file. It can be fixed by using -stdlib=libc++. And if I can't change  
arguments (or I need to setup root DNS and create fake sync), how to set  
libc++ as default Clang library?
CXXFLAGS="-stdlib=libc++" gclient sync didn't work.
