stella: fix compiler search in configure script

In configure script there are some tests that are looking for
a suitable compiler. For this purpose script tries to compile
and link some C++ code that is hardcoded in the body of script.

The problem is that only linker flags ($LDFLAGS) are passed to the
compiler when the script is compiling test code. Therefore some
necessary command line options can be lost and this would lead to
errors.

This exactly happens to ARC:
  1. -matomic option is lost as it compiler option,
  2. test code compilation fails,
  3. the script decides not to use arc-buildroot-linux-uclibc-g++,
  4. scipt checks host compiler (x86_64-linux-gnu-g++ in your case),
  5. package is being built for x86_64, not for ARC.

About last 2 steps - I don't know why configure script should try
to build stella for host machine. As for me an error should be
raised and a build should be stopped. But this is up to stella
developers.

Current patch adds compiler options ($CXXFLAGS) when compiling
test code in configure script.

Fixes stella build for ARC, e. g.:

ffmpeg: don't pass --enable-mipsfpu on non-MIPS platform

The current logic to pass the --{enable,disable}-mipsfpu option is:

ifeq ($(BR2_MIPS_SOFT_FLOAT),y)
FFMPEG_CONF_OPTS += --disable-mipsfpu
else
FFMPEG_CONF_OPTS += --enable-mipsfpu
endif

In practice, this means that on MIPS soft-float, --disable-mipsfpu is
passed, and that in *all* other cases, --enable-mipsfpu is passed,
including if we are *not* targetting the MIPS architecture.

Even though this doesn't seem to cause any problem, it is a bit weird to
see --enable-mipsfpu when you're building ffmpeg for a non-MIPS
architecture, so we better fix this by enclosing the MIPS-related
options in a MIPS condition.

ffmpeg: explicitly disable NEON support

When BR2_ARM_CPU_HAS_NEON=y, we pass --enable-neon. However, when
BR2_ARM_CPU_HAS_NEON is disabled, we don't pass anything. This generally
works fine, but turned out to integrate NEON code in ARMv7-M
builds (since it's ARMv7, ffmpeg assumed it should enable NEON code).

Even though ffmpeg is now disabled for ARMv7-M, it still makes sense to
be explicit, and disable NEON support when the CPU doesn't have it.

toolchain: Bump ARC tools to arc-2016.09-eng008

As described at:
4520524ba055706236db9f00dd79f1b2e2e87fde
this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng008.

Main updates were made for gcc. It was switched to GCC 6 and to
OSABI v4.

Besides this patch fixes buildroot ARC failures connected to
"crtbeginT.o" object file missing. This issue lead to two main errors:

1) "crtbeginT.o: No such file or directory", e. g. bootutils-1.0.0.
No comments are required here I hope.

2) Errors like "compiler cannot create executables", e.g.:
  a) host-gcc-final-arc-2016.09-eng007 static build,
  b) aespipe-2.4c.
That was caused because the test to determine if compiler is able to
create executables was failing due to missing "crtbeginT.o" file.

We still keep GDB as it is of arc-2016.03 release because there're some
issues we'd like to resolve before releasing it to wider audience.

So again note this is next engineering builds of arc-2016.09 series
and it might have all kinds of breakages, please don't use it for
production builds.

libaio: work-around for PowerPC issue

Both the blktrace and gadgetfs-test packages were failing to build on
PowerPC due to the mysterious:

  hidden symbol `_rest32gpr_30_x' in libgcc.a(e500crtresx32gpr.o) is referenced by DSO

Due to this error, we disabled blktrace on PowerPC in commit
0d8158fc619ce849b531d07b27da4ba9748d4ea4. However, gadgetfs-test
continued to fail with the same error. As Romain Naour pointed out, the
problem seems in fact to come from a common dependency of blktrace and
gadgetfs-test: libaio. As Romain investigated, the problem started
appearing after the last bump of libaio, from version 0.3.109 to
0.3.110.

A quick bisect through the libaio changes between 0.3.109 and 0.3.110
has revealed that the problematic change is one in the libaio build
system, which now obeys to the CFLAGS provided in the environment,
rather than overriding them. So the CFLAGS provided by Buildroot cause
this problem. It turns out that the problematic CFLAGS is -Os, which is
indeed known to cause issues on PowerPC in some corner cases.

Even though it would probably be a better long-term solution to switch
to -O2 by default, and mark -Os as not available on PowerPC, it is a too
radical change so close to 2016.08. So we simply adjust the libaio
package so that it uses -O2 instead of -Os.

ffmpeg: disable for ARMv7-M

In the ffmpeg code, libavutil/arm/asm.S makes some assumption about the
ARM architecture for which the code is built. Only ARMv4, ARMv5, ARMv6
and ARMv7-A is supported. Due to this, object files built out of
ARM-optimized assembly code have the wrong architecture information,
causing a failure at link time.

Adding ARMv7-M support would be possible, but it doesn't exist yet in
ffmpeg, and it's pretty unlikely that ffmpeg will ever be needed on an
ARMv7-M platform, so this commit takes the simple approach of disabling
ffmpeg for ARMv7-M.

lftp: fix static link with readline

When readline is static library, we need to link against ncurses,
it is because, dependent library's symbols are not resolved when
static library is built. Those symbols are resolved when binary tries
to link with static library.

We can't pass linker flags for ncurses by setting LIBS environment
variable via <PKG>_CONF_ENV because it looks like build system is not
taking that into account and even though it would have been, order of
linking is important.

We can't also pass linker flags for ncurses via --with-readline-libs
conf options because it causes lftp_LIB_READLINE macro to take readline
headers from host machine if available. To use --with-readline-libs
we need to set --with-readline=yes and --with-readline-inc to include
dir. But when --with-readline=yes, readline_prefix is computed based
on if headers can be found in /usr/local or /usr. If readline is
installed on host machine, then configure fails since we are using
headers for host machine. If headers are not found in /usr/local or /usr
then only path specified --with-readline-inc is taken into account.
So specifying linker flags for ncurses via --with-readline-libs will
not work in all cases.

So it looks like, updating linker flags directly is only option to fix
static link issue against readline.

openblas: fix build issues on ARM

This commit fixes several build issues of OpenBLAS on ARM:

 - The first one occured on ARMv5 platforms, when the ARMV5 OpenBLAS
   architecture is used. In this case, OpenBLAS build system forces
   -march=armv5, which may not be correct for certain toolchains. As an
   example, the Sourcery CodeBench toolchain has an ARMv4 and an ARMv5
   sysroot. The ARMv5 sysroot is actually an armv5te sysroot, so when
   OpenBLAS forces -march=armv5, gcc thinks it should use the ARMv4
   sysroot, causing build failures.

   To address this, a patch to completely remove the -march ARM CFLAGS
   is added to OpenBLAS.

   Fixes:

     http://autobuild.buildroot.net/results/991497b12b70f948169e5ad99eebd0fe7f6209a2/

 - The second one occured on ARMv7 platforms, when the ARMV7 OpenBLAS
   architecture is used. The OpenBLAS code expects an EABIhf build, so a
   dependency is added for EABIhf for both ARMv6 and ARMv7.

   Fixes:

     http://autobuild.buildroot.net/results/0ba0bee48a83367fcefab827e8eaa72f0c8fe90b/

 - Once the previous ARMv7 problem has been fixed, it turns out that the
   ARMv7 specific code in OpenBLAS contains VFPv3 specific
   code. Therefore, the user *must* have choosen either VFPv3 or VFPv4,
   or the code will not build. VFPv3-D16/VFPv4-D16 are not sufficient,
   as more than 16 registers are used by the OpenBLAS code.

   To address this, the ARMV7 platform of OpenBLAS is restricted to the
   proper VFPv3/VFPv4 selection, and the ARMV6 platform is restricted to
   the proper VFPv2 selection.

   This problem was not visible in the autobuilders, as it was hidden by
   the previous one.

libsigsegv: make the architecture dependencies more robust

While musl and glibc provide the ucontext structure definition on all
architectures they support, it is not the case of uClibc. We have been
excluding more and more architectures over time, but this isn't really
nice as we continuously need to add more. Latest example: the fact that
ucontext on ARM is only available on ARM platforms that support the ARM
instruction set (i.e not on the Thumb-2 only Cortex-M platforms).

Therefore, we introduce a BR2_PACKAGE_LIBSIGSEGV_ARCH_SUPPORTS variable,
which:

 - is set to 'y' for musl and glibc

 - is set to 'y' for uClibc for the only architectures that are known to
   provide ucontext (those are the ones that select ARCH_HAS_UCONTEXT in
   uClibc.

Note that we remove the comment, as it would become a way too
complicated comment, and we usually don't add comment for such
complicated situations (see libunwind for a similar example).

The webrtc-audio-processing configure script assumes that if the
host_cpu part of the tuple is "arm", then ARM instructions are
available. This is obviously incorrect for ARM Cortex-M platforms, which
only support the Thumb-2 instruction set.

In order to address this, we add a patch,
0001-configure.ac-fix-architecture-detection.patch, which changes how
webrtc-audio-processing detects the architecture: instead of relying on
the host_cpu part of the tuple, it relies on the built-in definitions of
the compiler.

Not only it fixes the Cortex-M detection, but it also enables ARMv7
optimizations on ARMv7-A: until now they were only enabled when the
host_cpu part of the tuple was armv7, which is never the case in
Buildroot.

However, once this issue is fixed for Cortex-M, the build nonetheless
fails later due to the usage of NPTL-only functions. So we change the
thread dependency to a NPTL dependency.

size-stats: fix bug when parsing file names with comma

The size-stats script fails when the usb_modeswitch_data is enabled,

iproute2: fix no-thread build

iproute2 believes that it needs to link with libpthread for its arpd
binary, because "some db implementations require thread". Therefore, our
iproute2.mk explicitly disables the build of arpd when thread support is
not available.

However, the sed expression it uses no longer works. The Makefile used
to look like:

TARGETS = foo baz baz arpd foobar

so replacing " arpd " with a space was working fine. However, the
Makefile got changed in iproute2 to:

ifeq (... berkeleydb available ...)
     TARGETS += arpd
endif

i.e, with no space at the end of the line. This made our sed expression
ineffective, causing build issues with no-thread configurations since
arpd was no longer disabled.

To address this, instead of sed-ing the Makefile, we overwrite the
berkeleydb detection of iproute2, by writing to the "Config" file, like
we're doing for other aspects of the package.

uclibc: proper thread default on m68k and Microblaze

Traditionally, Buildroot has a default of enabling thread
support. However, with the current construct of the thread choice in the
uclibc package, the m68k and microblaze architecture end up with no
thread support as the default.

In order to avoid having to explicit a more complicated "default" value
for the choice, we take a simple approach: we order the 3 possible
choices by order of "preference", since Kconfig selects the first
selectable option in a choice by default.

So, NPTL is first and is the default when available. Then comes
linuxthreads which only gets selected as the default when NPTL is
available. None is offered as a last choice (in the current
implementation, it is never the default, since all architectures can
have thread support, either through NPTL or linuxthreads).

[Thomas: reworked according to Yann's comment that we could rely on the
Kconfig behavior that selects the first available choice option.]

libunwind: fix architecture dependencies
