--- Comment #3 from Gert Wollny <gw.fossdev at gmail.com> ---
Given the patch in question explicitly adds CXX11_CXXFLAGS in a section that is
only taken into account when llvm is enabled the llvm version would also be
relevant. 

AFAIR the last version before llvm-7 that didn't advertise -std=c++11 was 
something like llvm-3.9, and there was a patch proposed by Emil that would bump
the minimum required version to 5.0 (it didn't land yet, I guess because there
was some andorid WIP patch in the series). With that support for -std=c++11
would become a requirement for builds that enable llvm.
