Make sure JE_CXXFLAGS_ADD uses CPP compiler
All the invocations of AC_COMPILE_IFELSE inside JE_CXXFLAGS_ADD were
running 'the compiler and compilation flags of the current language'
which was always the C compiler and the CXXFLAGS were never being tested
against a C++ compiler. This patch fixes this issue by temporarily
changing the chosen compiler to C++ by pushing it over the stack and
popping it immediately after the compilation check.
