In the Debian package of apache there's /etc/apache2/envvars. I'm not sure if this file appears in an out-of-the-box compilation of apache2. Anyway, /usr/sbin/apache2ctl looks for it and loads it before launching the server. The server in launched in the environment that is set in envvars. So you could try writing export LD_PRELOAD=... in envvars. I do not know if this has an effect on how apache2 spawns the CGI applications but you might give it a try.
