#122195# change cppu env, comid from generic cxx to s5abi (System 5 AMD64 ABI)

Patch by: Juergen Schmidt <jsc@apache.org>

Merged from r1534063 in the rejuvenate01 branch
#i122195# provide proper type_info for UNO exceptions on OSX 64bit

on OSX 64bit the class_type_info classes are specified
in http://refspecs.linuxbase.org/cxxabi-1.86.html#rtti but
these details are not generally available in a public header
of most development environments. So we define them locally.
