You can only do this for non setuid applications. I would question it
is even a bug. Execute only is an extremely vague concept anyway on
x86 since the chip doesnt really support it physically.

The convenience and usefulness of LD_PRELOAD seems to far outweigh this
consideration for normal use. Its probably one for the 'secure linux'
patch collection therefore.
