[BUG] GeneWeb7 CGI Debian 10 - Verbose on every page

[rogeriod]

Further to issue "GeneWeb7 CGI Debian 10" #1109 (now closed), I've updated the page https://geneweb.tuxfamily.org/wiki/Installing_GeneWeb_7_on_a_Raspberry_Pi_webserver with the instructions on how to compile the latest commit of GeneWeb7 and run it in CGI mode.

The issue reported now is that GW7 is printing some CGI related verbose on the bottom of each site page.

It seems that it is a bug in cgi mode, but compiling with --release flag (using ocaml configure.ml --release option) would not print these debug informations.

That has resolved the issue indeed - thank you!

I keep this opened since there is probably a bug in debug mode (:thinking:). I need to investigate and fix this (or not).
