Jose Quaresma 13aefbd92d buildhistory.bbclass: create the buildhistory directory when needed
When the BUILDHISTORY_RESET is enabled we need to move the
content from BUILDHISTORY_DIR to BUILDHISTORY_OLD_DIR but
when we start a clean build in the first run we don't have the
BUILDHISTORY_DIR so the move of files will fail.

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.
