Martin Jansa 86aaecf948 gio-module-cache.bbclass: disable update_gio_module_cache postinst script for nativesdk
* it fails to execute native binary inside the qemu usermode for target
  arch as shown e.g. for qemuarm and raspberrypi3 build on x86_64
  builder:

* it isn't needed in master, because nativesdk postinst were fixed by:
  commit d10fd6ae3fe46290c6e3a5250878966d9f12ca3f
  Author: Alexander Kanavin <alexander.kanavin@linux.intel.com>
  Date:   Mon Jun 11 16:38:20 2018 +0300
  Subject: qemuwrapper-cross: enable multilib and nativesdk variants of the script
* which depends on:
  commit d4f5b8e26acaadffac6df10f9a9d9ebfb3045f5f
  Author: Alexander Kanavin <alexander.kanavin@linux.intel.com>
  Date:   Mon Jun 11 16:38:17 2018 +0300
  Subject: gtk-immodules-cache.bbclass: convert cache creation to postinst_intercept mechanism

* backporting just these 2 isn't enough, we would need to backport
  something else as well, otherwise it fails with:
  webos-ndk-basic/1.0.0-1-r3/intercept_scripts-a4270d1427cca0a9d172dbcd8dc262957c8e081c657e1123cc9ad551d65f22ea/update_gio_module_cache-nativesdk:
  nativesdk-qemuwrapper: not found

  and at this point I would rather safely disable it for nativesdk
  in sumo instead of backporting bunch more commits to stable branch

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.
