zyre: bump version to fix static linking problem

The last tagged release of zyre, v1.0.0, was made in May 2014. Since
then, they have switched to pkg-config to detect zmq and czmq, which
fixes static linking problems. However, they made a number of changes
to configure.ac, which make it difficult to backport just the relevant
changes.

Since we already had another backported fix, let's simply bump the
version of zyre to the latest available commit, which builds fine with
no change for shared and static scenarios, thanks to the use of
pkg-config.

An issue was opened upstream to ask them to tag a new release:
https://github.com/zeromq/zyre/issues/324.

core/pkg-kconfig: fix configurators

Currently, the configurators are using $($(2)_MAKE_ENV), often derived
from $(TARGE_MAKE_ENV), as the environment to be set when calling the
various configurators.

This means that our host tools are used first, most notably pkg-config
(from host-pkgconf).

However, this is inherently flawed. Our pkg-config, when set for the
host, only searches .pc files in $(HOST_DIR) and never ever uses the
ones from the host. For example, since we do not build a host-qt, our
pkg-config would not find the host's QtCore.pc et al.

Consequently, on some systems (but not on others?) most of the
configurators fail to build, especially the latest kernel versions, as
they have been starting to use pkg-config two years ago.

Fix that by filtering-out sensible values out of the environment, but
only when calling the configurators.

[Thomas: rewrap comment to appropriate length.]

The dependency is changed from a 'select' to a 'depends on' to avoid a
circular dependency caused by the introduction of OpenCV-3. This means

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: fix setjmp/longjmp detection

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.

package/protobuf: needs dynamic libraries

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.

ola: Add patch to fix linking issue

This patch fixes this autobuild failure:

  http://autobuild.buildroot.net/results/e14/e14e1700d4fe359c56be57587bdb509e002e5753/build-end.log

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.

Built-tested with the config from the build bot, as well as with all OLA
options/plugins enabled.

Currently, sysstat uses CFLAGS to shoehorn the -lintl linker flags,

However, sysstat has a LFLAGS variable that, presumably, is to be used

toolchain/external: better check for gcc-5

gcc will always report a three-digit version sting, like 4.9.3 or 5.1.0.

For gcc before 5, we want to check the first two digits, while starting
with gcc 5, we are only concerned about the first digit.

So, change our matching code to test for the leading part of the version
string, up to the first dot after as-many version digit we're interested
in.

Note: we're adding the dot in the .mk code rather than in the Kconfig
symbol, because it seemed cleaner to do so.

As Thomas puts it:

    The comment can only be visible when a toolchain that is *not*
    uclibc and *not* glibc is used. I.e, the comment is now only visible
    when musl is used. Which is not what we want.

Indeed, I completely borked the conditions. When a glibc or uClibc
toolchain is selected, the comment is entirely hidden, and we don;t get
the extra requirements (wchar, !static).

package/libv4l: disable for musl toolchains

musl toolchains are not supported yet in libv4l but
it's a work in progress.

see:
http://git.linuxtv.org/cgit.cgi/v4l-utils.git/commit/?id=70570c6095fa5859cecd0f9522fe7fd749f1d554
http://git.linuxtv.org/cgit.cgi/v4l-utils.git/commit/?id=403a4e2697a1ff96fe2fa16589039595f21cadf0

But it's not enough.

Disable musl toolchains for libv4l 1.6.3 and wait for a new release.

[Thomas: update Config.in comment to take into account the uclibc or
glibc dependency.]
