I think there is only check for serf.h, and one check for compiling.
The compile test has an extra "-L/usr/local/serf/lib" flag, so I've
mentally referred to it as "the link test".
I've provided the entire serf section of the config.log file in a later
email, but the section I was referring to is:

Ah, bad comms on my part. I've always used --with-apr=/usr/local/apr
--with apr-util=/usr/local/apr, rather than naked arguments. I didn't
realise that was misleading.
