Richard Purdie 995f7985f6 reproducibile_build: Fix SDE file generation when unpack reruns
Currently, if an existing TMPDIR is rebuilt, do_fetch/do_unpack can rerun
but SDE would remain unchanged. This leads to different results compared
to a fresh build. An example change which triggered this is:
http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=cb4e69e6346a9fbeebf83a5d5397cacbd41d48b5

Instead, delete any existing SDE and recalculate if we're reunning.
Also rename and drop the do_ prefix since these are for tasks,
not functions.

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.
