__GXX_RTTI is only defined since g++ 4.3.2 and so we can't rely on its absence
as indicating the use of -fno-rtti switch with the older versions of the
compiler, only do this for g++ 4.3+.
Also define wxNO_RTTI from configure if --enable-no_rtti was used as we can't
always detect it automatically.
Closes #11955.

g++) or by editing project files with MSVC so test for it here too.
