Reduce RAM for NSD (authoritative name server)

[AquaL1te]

NSD on a Raspberry Pi uses ~130MB, sometimes more. I happen to have a chat with one of the NSD developers and he said that adding the compiler flags below would decrease memory usage. Performance impact on a Raspberry Pi would be minimal since NSD is already optimized for large queries and the hardware on a Raspberry Pi would never be able to reach the software bottleneck, the hardware just isn't powerful enough.

Below is what is in the debian/rules file and is used to compile NSD.
[code]
override_dh_auto_configure:
        dh_auto_configure -- \
               --with-configdir=/etc/nsd \
               --with-nsd_conf_file=/etc/nsd/nsd.conf \
               --with-pidfile=/run/nsd/nsd.pid \
               --with-dbfile=/var/lib/nsd/nsd.db \
               --with-zonesdir=/etc/nsd \
               --with-difffile=/var/lib/nsd/ixfr.db \
               --with-xfrdfile=/var/lib/nsd/xfrd.state \
               --with-max-ips=1024 \
               --disable-largefile \
               --disable-recvmmsg \
               --enable-root-server \
               --enable-mmap \
               --enable-ratelimit
[/code]

I would like to request the following flags as an addition to decrease the memory usage. I'll leave it at your discretion to implement this or not.
[code]
  --disable-radix-tree You can disable the radix tree and use the red-black
                          tree for the main lookups, the red-black tree uses
                          less memory, but uses some more CPU.
  --enable-packed Enable packed structure alignment, uses less memory,
                          but unaligned reads.
