package: refactor listing of extractor dependencies

Don't special case $(XZCAT) when constructing DL_TOOLS_DEPENDENCIES. The next
commit will introduce another extractor that automatically builds when not
installed. Introduce EXTRACTOR_DEPENDENCY_PRECHECKED_EXTENSIONS that lists
archive extensions for which the extractor is already checked in
support/dependencies/check-host-foo.mk. Use this in the newly introduced
extractor-dependency to populate DL_TOOLS_DEPENDENCIES.

package/mpd: add choice between version 0.19 and 0.20

MPD version 0.20 being affected by GCC PR libstdc++/64735 means no mpd package
available in Buildroot for the architectures NIOSII, ARMv4, ARMv5 and SPARCv8
until GCC 7 is released.

As the next Buildroot release is in 2017.02, which is before GCC 7 is expected
to be finished we add hidden config symbols to select the version branch to use.

Note, that we bumped the version from 0.19 to 0.20 quite recently within the
current Buildroot release cycle. This way we can keep the support for mpd on
the affected architectures, like ARMv5, until GCC 7 is out.

Note, that for the version 0.19 MPD requires libglib2.

musl: no SSP on i386 and PowerPC

Due to what appears a bug in gcc according to the musl developers, but
that the gcc developers don't want to fix, SSP support currently don't
work on i386 and PowerPC with musl.

Additional details can be found at:

  http://www.openwall.com/lists/musl/2016/12/04/2

OpenWRT and Alpine Linux both have musl and gcc patches to work around
the issue, but in the context of Buildroot, we at this point don't care
enough about SSP support specifically with musl on those architectures
to carry additional patches.

Currently, having SSP enabled with musl/i386 causes a number of build
failures in the autobuilders: cups, ipmiutil, openssh, ruby, stunnel,
sudo and mosh at least all fail to build because of this.

So we simply disable SSP support in the toolchain when musl is used on
i386 and PowerPC. The PowerPC case is not tested in the autobuilders,
but has been reproduced locally and is also fixed by this patch.

Fixes:

cbootimage: disable on musl

cbootimage uses non-standard u_intXX_t types instead of the C99 types
uintXX_t types, which prevents it from building with the musl C library.

A patch to fix this has been submitted upstream, but since there are
many many occurences of such types, the patch is a bit large to carry in
Buildroot, especially compared to the fact that having this package
building against musl is probably not a top priority.

So for now, simply disable this package on musl, until upstream fixes
the issue and releases a new version.

ntfs-3g: add security fix for CVE-2017-0358

Jann Horn, Project Zero (Google) discovered that ntfs-3g, a read-write
NTFS driver for FUSE does not not scrub the environment before
executing modprobe to load the fuse module. This influence the behavior
of modprobe (MODPROBE_OPTIONS environment variable, --config and
--dirname options) potentially allowing for local root privilege
escalation if ntfs-3g is installed setuid.

Notice that Buildroot does NOT install netfs-3g setuid root, but custom
permission tables might be used, causing it to vulnerable to the above.

ntfs-3g does not seem to have a publicly available version control system
and no new releases have been made, so instead grab the patch from Debian.

wget: bump to 1.19.1 to fix build issue

Due to the patches we have on wget 1.19, we need to
autoreconf. Unfortunately, when the autoreconfiguration process occurs
with host-gettext already built and installed, the build of wget fails
with a fairly weird error:

In file included from str-two-way.h:44:0,
from c-strcasestr.c:37:
./stdint.h:89:5: error: #if with no expression
#if

As explained in http://git.net/ml/bug-gnulib-gnu/2017-01/msg00067.html
and the links pointed by this page, this is due to an incompatibility
between the newer version of gnulib used in wget, and an older .m4 file
in gettext.

In the context of Buildroot, the easiest way to avoid the issue is to
not autoreconf wget. The wget project has conveniently released a 1.19.1
release, which contains our two patches, plus just one small feature
addition. It is therefore reasonable to apply this as a solution to this
build issue.

support/test-pkg: add option to limit the number of tests

Sometimes, it interesting to have a global overview of whether the
package builds at all or not, rather than test on all toolchains.

Add an option that allows testing on a limited set of randomly choosen
toolchains.

Libevent/libtool gets confused by the library order when statically linking
the sample programs and passes -lz before -lcrypto even though libcrypto
uses zlib.

/bin/bash ./libtool --tag=CC --mode=link .. -o sample/https-client \
sample/https-client.o sample/hostcheck.o \
sample/openssl_hostname_validation.o libevent.la \

sample/hostcheck.o sample/openssl_hostname_validation.o \

-lssl -lz -lcrypto

../libcrypto.a(c_zlib.o): In function `zlib_stateful_expand_block':
c_zlib.c:(.text+0x30): undefined reference to `inflate'

This is most likely fixable, but as the sample programs aren't installed /
used, simply skip building them to save time and work around this issue.

docs/manual: centralize recommendations about BR2_DL_DIR

We currently have two places where we recommend where BR2_DL_DIR
should be set: "Environment variables" and "Location of downloaded
packages". The former recommends setting BR2_DL_DIR in the .config,
the latter kind of endorses using ~/.bashrc.

We prefer suggesting the ~/.bashrc way since it avoids downloading the
same file multiple times, and anyway it's wise to have all the details
in a unique place. So remove the .config suggestion from "Environment
variables" and let it just point to "Location of downloaded packages".
