[PATCH 1/1] target-sdk-provides-dummy: set nostamp for do_package

[kai.kang]

From: Kai Kang <kai.kang@windriver.com>

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 the same build project with
following steps, it fails.

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
|  is trying to install files into a shared area when those files already exist. Those files
|  and their manifest location are:
|   .../tmp/pkgdata/qemux86-64/lib32-target-sdk-provides-dummy
|     (matched in manifest-qemux86_64-lib32-target-sdk-provides-dummy.packagedata)
|   .../tmp/pkgdata/qemux86-64/runtime/lib32-target-sdk-provides-dummy
|     (matched in manifest-qemux86_64-lib32-target-sdk-provides-dummy.packagedata)
|   ... snip ...
| Please verify which recipe should provide the above files.

Because target-sdk-provides-dummy is a virtual package, its sstate
caches are same for both qemux86 and qemux86_64. So when build
target-sdk-provides-dummy for qemux86_64, it re-uses the sstate cache
from qemux86 and then create file lib32-target-sdk-provides-dummy under
${PKGDATA_DIR} which should not and it conflicts with
lib32-target-sdk-provides-dummy too.

So make do_package always be executed to fix the issue. Because it is a
dummy package, it won't cost too much build time.
