Martin Jansa 570938d845 bc: use u-a for bc as well
* bc can be provided by busybox as well (e.g. if you have your own
  defconfig and forget to explicitly disable it:

  ), causing conflict in u-a:

  update-alternatives: Error: not linking /usr/bin/bc to /bin/busybox.nosuid since /usr/bin/bc exists and is not a link

  and then whole do_rootfs or do_populate_sdk to fail because busybox postinst is failing:

  do_populate_sdk: Postinstall scriptlets of ['busybox'] have failed. If the intention is to defer them to first boot,
  then please place them into pkg_postinst_ontarget_${PN} (). Deferring to first boot via 'exit 1' is no longer supported.

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.
