If you grep for -pie in config.log you get this:

IO_LIB_LDFLAGS='-L/usr/lib/i386-linux-gnu -lstaden-read -fPIE -pie -Wl,-z,relro -Wl,-z,now -lm -lpthread   -lcurl -lz'

which was apparently generated by:

$ io_lib-config --libs
-L/usr/lib/i386-linux-gnu -lstaden-read -fPIE -pie -Wl,-z,relro -Wl,-z,now -lm -lpthread   -lcurl -lz

This will have to be fixed in libstaden-read-dev.
