There is this patch to ensure that __cxa_finalize gets linked into
non-shared executables. However, it didn't fix the python problem.
Don't know why and that's why the patch isn't installed. There's
some other issue when shared libraries are opened with dlopen.
Note that this just pulls in the stub version of __cxa_finalize
from libgcc_stub.a that does nothing. The same fix could be used
for _Jv_RegisterClasses but probably HP Java probably needs a real
working version of _Jv_RegisterClasses.
