Kai Kang 254ab4a764 target-sdk-provides-dummy: resolve sstate conflict
It exists a situation that there is a common config file includes
multilib.conf but variable MULTILIBS is not set by default:

  require conf/multilib.conf
  MULTILIBS ?= ""

When build target-sdk-provides-dummy in a build project, it fails with
following steps:

1 $ echo 'MACHINE = "qemux86"' >>conf/local.conf
  $ bitbake target-sdk-provides-dummy
2 $ cat <<EOF >>conf/local.conf
    MACHINE = "qemux86-64"
    MULTILIBS = "multilib:lib32"
    DEFAULTTUNE_virtclass-multilib-lib32 = "i586"
    EOF
  $ bitbake target-sdk-provides-dummy
  $ bitbake lib32-target-sdk-provides-dummy

It fails to build lib32-target-sdk-provides-dummy with error messages:

| ERROR: target-sdk-provides-dummy-1.0-r0 do_packagedata: The recipe target-sdk-provides-dummy

Add related directories to SSTATE_DUPWHITELIST to avoid the failures.

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.
