Martin Jansa 70aeecf62d *-initramfs: don't use .rootfs IMAGE_NAME_SUFFIX
* fixes the issue when image-live.bbclass expects the image
  ending with just INITRAMFS_FSTYPES:
  image-live.bbclass:INITRD_LIVE ?= "${DEPLOY_DIR_IMAGE}/${INITRD_IMAGE_LIVE}-${MACHINE}.${INITRAMFS_FSTYPES}"
  while by default it now was with .rootfs suffix:

  initramfs images aren't normally used for rootfs, so just set
  the suffix to empty, people using different artifact names might
  still need to set INITRD_LIVE (e.g. when their images don't end
  with "-${MACHINE}" as well)

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.
