OK, thanks for pointing this out. But you can still make the binaries
use LD_xxx if you want.

There should be a secure LD_PRELOAD equivalent - use a system-wide config
file instead of environment variables. I think David Engel is working on
it (specifying libraries to preload in /etc/ Is it OK
for zlibc, or does every user really have to be able to redefine library
calls on their own? (/etc/ would be useful for other things
as well, like replacing crypt() with something better.)
