samba4 picks up dbus as dependency if it was built before:
Checking for dbus : yes
Checking for header dbus/dbus.h : yes
Checking for library dbus-1 : yes
There is no configure option to control dbus support so we just make
sure dbus is built before samba4 to have reproducible builds.

could be solved by applying

The gnutils code uses __attribute__((constructor)) and
__attribute__((destructor)) to call constructor/desctructor when a
shared library is loaded.
Constructor/desctructor are not used when a static library is used
(except when if -Wl,--whole-archive -lgnutls -Wno-whole-archive is
used, not tested).
Even if gnutls initialization (_gnutls_global_init()) may be
called manually, the gnutls maintainer said it's not supported [1].
"Note that static linking applications with gnutls is not something
supported. gnutls relies on library constructors and destructors
which are not loaded when linking statically."
Now the gnutls script warns about static linking [2].
So disable gnutls statically by adding "depends on !BR2_STATIC_LIBS"
at Kconfig level and --disable-static in GNUTLS_CONF_OPTS.

Fixes CVE-2017-2619:
All versions of Samba prior to 4.6.1, 4.5.7, 4.4.11 are vulnerable to
a malicious client using a symlink race to allow access to areas of
the server file system not exported under the share definition.
Samba uses the realpath() system call to ensure when a client requests
access to a pathname that it is under the exported share path on the
server file system.
Clients that have write access to the exported part of the file system
via SMB1 unix extensions or NFS to create symlinks can race the server
by renaming a realpath() checked path and then creating a symlink. If
the client wins the race it can cause the server to access the new
symlink target after the exported share path check has been done. This
new symlink target can point to anywhere on the server file system.
This is a difficult race to win, but theoretically possible. Note that
the proof of concept code supplied wins the race reliably only when
the server is slowed down using the strace utility running on the
server. Exploitation of this bug has not been seen in the wild.

The ncurses sub-options BR2_PACKAGE_NCURSES_TARGET_{FORM,MENU,PANEL}
are currently very badly broken: they only control whether the
libform, libmenu and libpanel libraries are installed in
$(TARGET_DIR), but do absolutely nothing about their installation in
$(STAGING_DIR).
This means that when one of those options is disabled, the
corresponding library is indeed not installed in the target, but is
available in staging. It can therefore be detected by the configure
script of another package and used... even though the library will not
be in the target, causing a runtime failure.
Internally, ncurses.mk uses the "make install" logic of ncurses for
the staging installation, but uses a completely hand-written logic for
the target installation, which is the reason for this
desynchronization between what's installed in staging and target.
When BR2_PACKAGE_NCURSES_WCHAR=y, this also causes some build
failures. Indeed, when BR2_PACKAGE_NCURSES_WCHAR=y, Buildroot creates
some symbolic links lib<foo>.so -> lib<foo>w.so in staging and target,
but only for the lib<foo> that have been enabled by
BR2_PACKAGE_NCURSES_TARGET_{FORM,MENU,PANEL}. Due to this, a package
that for example needed the libmenu library but forgot to select
BR2_PACKAGE_NCURSES_TARGET_MENU was:
- Building fine with BR2_PACKAGE_NCURSES_WCHAR disabled (because
libmenu.so exists in staging), but would fail to run at runtime
because libmenu.so is not in the target.
- Fail to build with BR2_PACKAGE_NCURSES_WCHAR=y because only
libmenuw.so exists, and not the libmenu.so symbolic link.
Since those libraries are small (43K for libform, 21K for libmenu and
8.2K for libpanel), this commit takes the very simple approach of
removing those options, and installing the libraries
unconditionally. It therefore uses the "make install" logic for both
the staging *and* target installation.
In detail, this commit:
- Removes the NCURSES_PROGS variable, not needed since
--without-progs already allows to disable the build and
installation of programs.
- Removes the NCURSES_LIBS-y variable, and replaces it with a single
unconditional assignement to NCURSES_LIBS, only used to create the
lib<foo>w.so -> lib<foo>.so symbolic links when wchar support is
enabled.
- Removes NCURSES_INSTALL_TARGET_CMDS and the functions it was
calling: NCURSES_INSTALL_TARGET_LIBS and
NCURSES_INSTALL_TARGET_PROGS.
- Adds a NCURSES_TARGET_SYMLINK_RESET hook to create the reset ->
tset symbolic link, as was done before.
- Adds a NCURSES_TARGET_CLEANUP_TERMINFO to cleanup the terminfo
files in the target, so that we stay in the same situation in terms
of installed terminfo files.
- Removes the BR2_PACKAGE_NCURSES_TARGET_{FORM,MENU,PANEL} options
from the Config.in files: both their definition and usage.
- Simplifies all the symlink dance for lib<foo> -> lib<foo>w, because
as Yann E. Morin suggested, this dance is only needed in staging, not
in the target. Once binaries have been built, they refer to the
SONAME of the library, which is the lib<foo>w variant (for shared
linking). For static linking and .pc files, it's obvious that we
don't care about them on the target. Therefore the
NCURSES_LINK_LIBS_STATIC, NCURSES_LINK_LIBS_SHARED and
NCURSES_LINK_PC functions no longer take any argument: they always
apply to STAGING_DIR only. NCURSES_LINK_TARGET_LIBS is removed.
It is worth mentioning that adding Config.in.legacy support is *NOT*
necessary. Indeed:
- If they were disabled before this patch, having them in
Config.in.legacy would not trigger the legacy warning.
- If they were enabled before this patch, then the behavior is
unchanged: all libraries are now unconditionally installed. So
there is no point in warning the user.
We double-checked the installed size of a filesystem containing just
ncurses before and after this patch, and the only folder that has its
size changed is /usr/lib, growing from 852 KB to 932 KB in the wchar
enabled case. That's a 80 KB system size increase.
This commit fixes the sngrep build failure and potentially numerous
runtime issues with ncurses.

samba4 relies on the $ORIGIN feature of the dynamic linker, which used
to not be implemented in old uClibc versions. However:
- this feature is supported by glibc
- this feature is supported by uClibc-ng, which is the only uClibc
version we are going to support
- this feature is supported by musl
Consequently, we can completely remove the dependency of samba4 on

Note that despite this commit, samba4 still cannot be chosen when the
musl C library is used, because samba4 requires native RPC support,
