Richard Purdie f5fd1c2fd3 bitbake: fetch2/git: Avoid races over mirror tarball creation
There is a potential race over the mirror tarballs where a partial git repo
could be extracted causing fetcher failures if the tarball is being rewritten
whilst another build accesses it.

Create the mirror tarball atomically to avoid this.

[YOCTO #14441]

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.
