You should forget to think in inverted RewriteCond/RewriteRule terms
and start to think in human natural locations:

     location / {
         ...
         error_page  404  = /index.php?q=$request_uri;
     }

     location /filestore/ {
         ...
     }

     location /tmp/ {
         ...
     }

     location /cgi-bin/ {
         ...
     }
