Compiler that are known to support C++11 (gcc >= 4.3 and clang) are now used in this mode by default. It is still possible to override this choice using --(en|dis)able-cxx11. Moreover, c++11 mode is detected from the compiler itself, not from the use of --enable-cxx11. This allows to support compilers other than gcc or clang. Update INSTALL file accordingly and clean it a little bit.
