Alex Kiernan e3037b54ea systemd: Reinstate systemd-hwdb-update.service 
systemd supports a distribution hwdb.bin in /usr/lib/udev/hwdb.bin,
which is used if /etc/udev/hwdb.bin is not present. When generating the
install time hwdb, for systemd, ensure that we put it in /usr/lib/udev,
which then ensures that at boot time we do not regenerate it, unless the
system is marked for update.

This allows fragments dropped into /etc/udev/hwdb.d to be processed
correctly, but without requiring a first boot time build:

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.
