Joshua Watt 632bbf4bd7 classes/reproducible_build: Read SDE file later
Defers the resolution of the SOURCE_DATE_EPOCH until the variable needs
to be actually realized with a value. The previous method of loading the
value in anonymous python had issues because it could occur before other
anonymous python functions that affect the location of the epoch file,
such as when a recipe uses AUTOINC/AUTOREV or allarch.bbclass.

Also adds more logging to help diagnose issues in the future.

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.
