Martin Jansa 08eb8565b6 sstate.bbclass: catch ValueError from incorrectly written sstate manifests
* in some rare cases the file format might be broken, e.g. when you run
  out of disk space while writing to it (hint: make sure to use
  BB_DISKMON_DIRS on _all_ the builds, to make sure that they can stop
  gracefully before this happens).

* will show error like this:
  ERROR: Invalid line '/OE/build/luneos-thud/webos-ports' in sstate manifest '/OE/build/luneos-thud/webos-ports/tmp-glibc/sstate-control/index-allarch'
  when the file isn't complete, like in my case:
  $ tail -n 2 /OE/build/luneos-thud/webos-ports/tmp-glibc/sstate-control/index-allarch
  /OE/build/luneos-thud/webos-ports/tmp-glibc/stamps/all-webos-linux/org.webosports.app.calculator/0.1.1+gitrAUTOINC+9e9eb67c28-r0 /OE/build/luneos-thud/webos-ports/tmp-glibc/sstate-control/manifest-allarch-org.webosports.app.calculator /OE/build/luneos-thud/webos-ports/tmp-glibc/work/all-webos-linux/org.webosports.app.calculator/0.1.1+gitrAUTOINC+9e9eb67c28-r0
  /OE/build/luneos-thud/webos-ports

* instead of much longer exception which doesn't really show what's
  wrong to selectively fix that (other than removing while TMPDIR):

  ERROR: Command execution failed: Traceback (most recent call last):

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.
