Thanks for your suggestion. I don't think this works with LD_PRELOAD. Sudo
sets LD_PRELOAD to /usr/local/libexec/sudo_noexec.so which is the full path
including the shared library. I don't think the dynamic linker will
magically change this to /usr/local/libexec/64/sudo_noexec.so for 64 bit
linking.
