[OE-core] [meta-fsl-ppc][PATCH] bitbake.conf: add PKGDATA_DIR to BB_HASHBASE_WHITELIST

[ting.liu at freescale.com]

From: Ting Liu <b28495 at freescale.com>

In meta/conf/bitbake.conf, PKGDATA_DIR is default to:
PKGDATA_DIR = "${STAGING_DIR_HOST}/pkgdata"

But in meta/conf/multilib.conf, PKGDATA_DIR is set as:
PKGDATA_DIR = "${STAGING_DIR}/${MACHINE}/pkgdata"

When multilib enabled, linux-libc-headers cache will be machine
specific:
$ bitbake-diffsigs sstate-cache/1a/sstate:linux-libc-headers:ppce6500-poky-linux:3.17.7:r0:ppce6500:3:1a0c3934d91479fd7242a5b1d407d155_package.tgz.siginfo sstate-cache/28/sstate:linux-libc-headers:ppce6500-poky-linux:3.17.7:r0:ppce6500:3:28c918e8f9f4a4cfceb3a38b258f7501_package.tgz.siginfo
basehash changed from 8d3158bbddcee612fa30badd05f47b8e to 68ac258fc6c8e489f360fde3123a5894
Variable MACHINE value changed from 'b4420qds' to 'b4860qds'
