Martin Jansa 4e05a42b93 iputils: add PACKAGECONFIG for libidn and disable it by default
* it got enabled by default, but without the dependency on libidn in:
  commit 5997981fa2c22609a88b8cbb595dbf7758b2f7c2
  Author: Alexander Kanavin <alexander.kanavin@linux.intel.com>

  Subject: iputils: update to 20161105

* https://github.com/iputils/iputils/blob/master/RELNOTES.old
  mentiones that IDN was enabled by default in:
  [s20160308] and surprisingly the same in [s20150815]
  but there are no release notes for s20151218 version we were using until
  now, don't know how it really relates to [s20150815].

* but there are some issues with libidn as described in:
  https://github.com/iputils/iputils/commit/f3a461603ef4fb7512ade3bdb73fe1824e294547
  so disable it by default.

* fails with:
  | In file included from ping_common.c:1:0:
  | ping.h:39:10: fatal error: idna.h: No such file or directory
  |  #include <idna.h>
  |           ^~~~~~~~

* Easiest way to reproduce this failure is to remove libidn from gnutls
  PACKAGECONFIG or to use gnutls which doesn't have libidn PACKAGECONFIG
  at all (like the one in meta-gplv2).

* First it leads to following QA issue:
  http://errors.yoctoproject.org/Errors/Build/53212/
  ERROR: iputils-s20161105-r0 do_package_qa: QA Issue: iputils-ping rdepends on libidn, but it isn't a build dependency, missing libidn in DEPENDS or PACKAGECONFIG? [build-deps]
  ERROR: iputils-s20161105-r0 do_package_qa: QA Issue: iputils-traceroute6 rdepends on libidn, but it isn't a build dependency, missing libidn in DEPENDS or PACKAGECONFIG? [build-deps]
  ERROR: iputils-s20161105-r0 do_package_qa: QA run found fatal errors.
  Please consider fixing them.
  ERROR: iputils-s20161105-r0 do_package_qa: Function failed:
  do_package_qa
  ERROR: Logfile of failure stored in: /OE/build/oe-core/tmp-glibc/work/core2-64-oe-linux/iputils/s20161105-r0/temp/log.do_package_qa.7627
  ERROR: Task (/OE/build/oe-core/openembedded-core/meta/recipes-extended/iputils/iputils_s20161105.bb:do_package_qa) failed with exit code '1'

* But if you cleansstate iputils as well (after removing libidn from
  gnutls PACKAGECONFIG) to empty iputils RSS, then you get the error about
  missing idna.h:
  http://errors.yoctoproject.org/Errors/Build/53213/

* Adding the libidn dependency explicitly in iputils recipe fixes the
  issue.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
