Richard Purdie 116b22a1ce sstate: Avoid deploy_source_date_epoch sstate when unneeded
This sstate task is only needed when depended upon, it can be skipped
if there are no tasks running that directly depend upon it.

This reduced the number of sstate tasks in something like an image
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.
