The commits need to be squashed, but please test.
The distribution of the recursor now works the same as dnsdist (cd pdns/recursordist; autoreconf -i; ./configure; make dist), please the the tarballs generated from make dist.
cd pdns/recursordist; autoreconf -i; ./configure; make dist
Apart from checking in both the ext/ symlink forest and the .py making it, this LGTM.
Autotoolize the recursor
This is done similar to dnsdist.
This commit adds a pdns_check_os.m4 to set OS dependent options.
Recursor: have buildscripts use new normal configure
Appease the license-gods
