courier (0.58 and all older versions I've tested) fails with Linking when 
using LDFLAGS="-Wl,--as-needed".

Reproducible with
LDFLAGS="-Wl,--as-needed" ./configure
LDFLAGS="-Wl,--as-needed" make

--as-needed tells the linker to only link libraries with functions that are 
actually in use. Failure usually means that the linking order is wrong at 
some place. I didn't find a bugtracker for courier, so I'm posting it here.

Output:
