tdf#121131: Default COMPILER_PLUGINS_CXX to g++ -std=c++11
ab8bf5533f8de9bb1aa9dc83e650e4eccf0fcac3 "Avoid error message from configure
about clang's header for compiler plugins" caused problems after
cd472d1d8489f30797f47d3f6dafede28c1feb90 "Compile as C++2a, where available",
when the compiler used to build LO (CXX) supports -std=gnu++2a but the compiler
used to build loplugin (COMPILER_PLUGINS_CXX) does not. So solve that problem
instead by just adding -std=c++11 to the default for COMPILER_PLUGINS_CXX.
