If an existing source date epoch file was found during do_unpack, it was deleted and a new one would be written in its place. This causes a race with check-before-use code in get_source_date_epoch_value. Resolve the problem by making do_unpack write the new source date epoch to a temporary file, then do an atomic rename to ensure it's always present, and change the check-before-use code to use a EAFP exception instead of checking for file existence.

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.
