autoconf: Updated (2.68 -> 2.69)
automake: Updated (1.11.1 -> 1.11.6)
automake: fixed typo in .conf file
automake: changed to also create a /usr/share/aclocal symlink

Besides creating a symlink automake -> automake-$version in /usr/share we are
now creating one for aclocal -> aclocal-$version too.
iproute2: Updated (3.4.0 -> 3.10.0)
ulogd2: Updated (2.0.1 -> 2.0.2)
automake: add linux-musl support to automake's config.sub

As this config.sub is used when regenerating autotools related files by
running 'autoreconf' the newly generated configure script will include
support for linux-musl by default.
ipset: fixed to not check for kernel sources
ipset: fixed libipset/data.h to include sys/types.h for getting size_t
libnetfilter_queue: fixed headers that miss to include sys/types.h to get u_int*_t types
ulogd2: fixed raw2packet filter to include <linux/types.h> to get __be{16,32} types
ulogd2: fixed to not use the FILE struct as marker to check if the user requested to use syslog

Do not use the FILE struct as marker to check if the user requested to use
syslog.

In musl the FILE struct is opaque, thus its storage size is not known to
the application.
This means that when using musl it has to be use as a pointer like it was
intended to be used.
musl: Updated (0.9.12 -> 0.9.13)
iptables: Updated (1.4.16.3 -> 1.4.20)
ppl: fixed regression after automake update from 1.11.1 -> 1.11.6
musl: fix iptables package
libnfnetlink: fix build against musl libc
musl: fix libnetfilter_queue by defining _GNU_SOURCE to expose struct tcphdr
ulogd2: fixed musl build by adding an internal copy of sys/queue.h

This case was detected when trying to build ulogd2 on a musl libc based
environment, because musl doesn't provide <sys/queue.h>.

according to a short discussion on #musl:

dalias> sys/queue.h has nothing to do with libc. it's a linked list/queue
        implementation entirely in a header file
musl: fixed ulogd2 by defining _GNU_SOURCE for exposing struct tcphdr
