Both of CONFIG_NF_CONNTRACK and CONFIG_NF_CONNTRACK_MARK are needed by
xtables-addons.
Although the current code does enable them in the linux' .config file,
the former is protected behind CONFIG_NETFILTER_ADVANCED, which may be
missing from a user-supplied (def)config file, and is missing from some
of the bundled defconfigs as well.
For example, the following defconfig fails to build:
BR2_TOOLCHAIN_EXTERNAL=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_DEFCONFIG="i386"
BR2_PACKAGE_XTABLES_ADDONS=y
So, also force-enable CONFIG_NETFILTER_ADVANCED.

Too often the question is raised, that ipkg, opkg and rpm do not work,
and users complain they can not install packages.
Even though we do have a clear and clearly explained section in our
manual, people do not read it (when will users read manuals? sigh...).
So, add a big fat comment about ipkg/opkg/rpm, that Buildroot does not
generate binary packages and does not provide any package database for
any of those package manager.

libselinux causes some build problems due to the toolchain on ARC,
which haven't been solved so far. As a temporary solution for Buildroot
2015.08, this commit makes libselinux (and its reverse dependencies)
unavailable on ARC. Of course, once the toolchain problem is
addressed, this commit can be reverted to re-enable libselinux on ARC.

This commit adds a patch to Boost to make it use the eventfd()
function provided by the C library when uClibc is used, rather than
falling back to using directly the __NR_eventfd system call. This
fixes the build on ARC, which doesn't define __NR_eventfd.
The original problem is that uClibc pretends to be glibc 2.2, which
didn't had eventfd(), so Boost makes the system call
manually. uClibc-ng, in its next release, will pretend to be glibc
2.10 (see
http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/?id=4ff3a6c8eb91db71d6dc3d2932b66e848bd20ac3),
which will also fix the problem, but requires bumping the uClibc
version, rebuilding the external toolchains, and so on.
Ideally, Boost should be doing a compile test to detect if eventfd()
is available or not, but the Boost build system is so brain-damaged
that doing so would require way too much effort.

libpthsem has been affected since quite a while by build issues, but
occuring only on Nathaniel Roach's autobuilder. The failure message
is:
error: #error "Unsupported Linux (g)libc version and/or platform"
This message comes from pth_mctx.c file, which implements five methods
for machine context initialization:
VARIANT 1: THE STANDARDIZED SVR4/SUSv2 APPROACH
VARIANT 2: THE SIGNAL STACK TRICK
VARIANT 3: LINUX SPECIFIC JMP_BUF FIDDLING
VARIANT 4: INTERACTIVE SPECIFIC JMP_BUF FIDDLING
VARIANT 5: WIN32 SPECIFIC JMP_BUF FIDDLING
The "Unsupported (g)libc version and/or platform" only appears when
"VARIANT 4" is used, since VARIANT 4 only supports a very limited
number of platforms. So when building with Nathaniel's autobuilder,
VARIANT 4 is chosen.
However, when you build libpthsem on some other machine than
Nathaniel's autobuilder, VARIANT 2 is chosen, and works regardless of
the glibc version or architecture.
VARIANT 2 is chosen when:
!PTH_MCTX_DSP(sjljlx) &&\
!PTH_MCTX_DSP(sjljisc) &&\
!PTH_MCTX_DSP(sjljw32)
On both Nathaniel's autobuilder, and on a different machine, the
PTH_MCTX_MTH macro gives sjlj:
#define PTH_MCTX_MTH_use PTH_MCTX_MTH_sjlj
However, on a "normal" machine, the PTH_MCTX_DSP macro gives ssjlj:
#define PTH_MCTX_DSP_use PTH_MCTX_DSP_ssjlj
While on Nathaniel's autobuilder, it gives:
#define PTH_MCTX_DSP_use PTH_MCTX_DSP_sjljlx
This explains why VARIANT 4 is being used on Nathaniel's autobuilder,
while VARIANT 2 is used when building on other platforms.
The decision of the value for PTH_MCTX_DSP is derived as follows in
configure.ac:
AC_CHECK_SJLJ(sjlj=yes, sjlj=no, sjlj_type)
[...]
elif test ".$sjlj" = .yes; then
mctx_mth=sjlj
mctx_dsp=$sjlj_type
[...]
AC_DEFINE_UNQUOTED(PTH_MCTX_DSP_use, [PTH_MCTX_DSP_$mctx_dsp], [define for machine context dispatching])
So basically, the value of PTH_MCTX_DSP is $sjlj_type, as returned by
the AC_CHECK_SJLJ autoconf macro, implemented in
acinclude.m4. However, reading this macro is quite informative: it
does a number of tests that are not cross-compile
friendly. Especially, it looks at the kernel version with 'uname -r'
to decide whether the Linux system is braindead or not. If the system
runs a 2.2.x kernel or newer 2.x, or a 3.x kernel, everything is fine,
the system is not braindead, and sjlj_type is set to ssjlj. However,
if the build system runs a 4.x kernel, then it is considered as
braindead, and sjlj_type is set to sjljlx.
And indeed, Nathaniel's autobuilder is running a 4.x kernel, while all
other autobuilders run 2.x or 3.x kernels.
Since for all sane Linux systems, this AC_CHECK_SJLJ macro concludes
that the setjmp/longtmp type is ssjlj, this commit takes the simplest
route of forcing this value, skipping the broken detection.
Note that we're overriding ac_cv_check_sjlj instead of using the
--with-mctx-* options, since the latter do not work properly in the
context of Nathaniel's autobuilder, as the broken cross-compilation
tests continue to cause problems.

Eventhough it should be theoretically possible to build protobuf in
static-only, configure.ac includes an m4 macro, ACX_PTHREAD defined in
m4/acx_pthread.m4, which forcibly checks for threads *with* shared libs,
and is completely broken for static-only (as it forces -shared whatever
the user selection), ending up with these configure results:
checking for the pthreads library -lpthreads... no
checking whether pthreads work without any flags... no
checking whether pthreads work with -Kthread... no
checking whether pthreads work with -kthread... no
checking for the pthreads library -llthread... no
checking whether pthreads work with -pthread... yes
checking for joinable pthread attribute... PTHREAD_CREATE_JOINABLE
checking if more special flags are required for pthreads... no
checking whether to check for GCC pthread/shared inconsistencies... yes
checking whether -pthread is sufficient with -shared... no
checking whether -lpthread fixes that... no
checking whether -lc_r fixes that... no
configure: WARNING: Impossible to determine how to use pthreads with shared libraries
checking whether what we have so far is sufficient with -nostdlib... no
checking whether -lpthread saves the day... no
configure: WARNING: Impossible to determine how to use pthreads with shared libraries and -nostdlib
Fixing this macro is far from trivial; protobuf in a static-only
scenario is probably not too common. So, just disable protobuf for
static-only builds.

The problem is caused by the -fvisibility-inlines-hidden switch.
Removing the switch is probably the least intrusive way we can make the
problem go away. The first solution that was considered was to move the
definition of the offending method to the .cpp file. However, with
other combinations of compilers and platforms, I suppose it could happen
with other methods as well. Removing the switch ensures we catch them
all.

Set `DBG` to an empty value to disable -Werror when building libpfm4. Build
aborts with a musl toolchain because of warnings about redirecting incorrect

So -Werror shouldn't be used in released code since it can cause random build
failures on moderate warnings. It also depends on the used toolchain since
different toolchains may or may not print the same warnings.

For gcc before 5, we want to check the first two digits, while starting

So, change our matching code to test for the leading part of the version
