Max Krummenacher 194ce1539e util-linux: Use update-alternatives for fsfreeze, nsenter
busybox may also provide a fsfreeze and nsenter implementation,
so use u-a to allow installing them side by side.
If one installs both, busybox and util-linux, one gets the following error
(seen on a populate-sdk run):

| ERROR: 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.

And the coresponding do_populate_sdk extract:

| ...
| update-alternatives: Error: not linking ...sdk/image/usr/local/oecore-x86_64/sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/sbin/fsfreeze
|     to /bin/busybox.nosuid /bin/busybox.nosuid since ...sdk/image/usr/local/oecore-x86_64/sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/sbin/fsfreeze
|     exists and is not a link
| ...

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.
