[ldns-users] adding (partial) Python3 support

[Patrik Fältström]

Did not have autoremake, but autheader existed and solved that problem. Now configure is done.

Next issue, libtool:

$ make
./install-sh  -c -m 644 ldns/error.h ./include/ldns/
./libtool --tag=CC --quiet --mode=compile gcc -I. -DHAVE_CONFIG_H -Wwrite-strings -W -Wall -O2 -g -I/opt/local/include -c rdata.c
make: ./libtool: No such file or directory
make: *** [rdata.o] Error 1
$ which libtool
/usr/bin/libtool
$ ln -s /usr/bin/libtool .
$ make
./libtool --tag=CC --quiet --mode=compile gcc -I. -DHAVE_CONFIG_H -Wwrite-strings -W -Wall -O2 -g -I/opt/local/include -c rdata.c
./libtool: unknown option character `-' in: --tag=CC
