Document restrictions on mixing -fno-rtti and -frtti

http://gcc.gnu.org/onlinedocs/gcc-4.4.3/gcc/C_002b_002b-Dialect-Options.html#index-fno_002drtti-148 doesn't mention any restrictions on compiling programs with some translation units compiled with -frtti, and others compiled with -fno-rtti. Yet there are such restrictions. For example, programs don't link when a -frtti class is derived from a -fno-rtti base class. Any restrictions like that should be documented or fixed.
