Joshua Watt 1c66128e7e classes/archiver: run do_unpack_and_patch after do_preconfigure
The commit 8a7c779487 ("classes/archiver: Create patched archive before
configuring") fixed a race condition when using the archiver, but
introduced a bug where the GCC source would occasionally be deleted due
to the archiving code running before do_preconfigure. Instead, make sure
the archiving code runs after do_preconfigure by making
do_unpack_and_patch depend on it. This makes more sense anyway since
do_preconfigure is effectively an extension of do_patch.

This fixes errors like:

 cat: .../gcc/defaults.h: No such file or directory

when making certain configuration changes

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.
