* when ld-is-gold is used, merge_config.sh silently fails and doesn't generate anything
  useful in .config (and also include directory isn't created):

  CONFIG_LOCALVERSION="-yocto-standard"

* and because the failure is silent, it will happily start building
  kernel with default defconfig, which even builds OK for qemux86-64
  but on qemux86 I've noticed this issue, because incorrectly
  configured kernel build fails with:

  ]because merge_config.sh is redirected to work-shared/qemux86/kernel-source/.kernel-meta/cfg/merge_config_build.log
  and bbfatal_log called in do_kernel_configme only when merge_config.sh fails which it should in this case
  but doesn't.

  The merge_config_build.log shows 5.4 specific error:
    scripts/Kconfig.include:39:  gold linker 'i686-oe-linux-ld' not supported
  but then it happily continues reporting what isn't applied in not created
  .config file

* I don't know why merge_config.sh uses separate more difficult to find merge_config_build.log
  instead of leaving the output to end in log.do_kernel_configme, I'll send it as separate
  commit so that it can be discussed there.
