[PATCH 0/5][RFC v4] Machine specific sysroot implementation

[Dongxiao Xu <dongxiao.xu@intel.com>]

Hi Richard,

This RFC is the 4th version of machine specific sysroot implementation.
Please help to review.

I tested the build of "poky-image-sdk" and "meta-toolchain-sdk" for atom-pc and emenlow in the same build directory if change emenlow's architecture to core2, and the test could be passed.

Changes from v3:
1) Make bb.build.stampfile() to be the main entry point so most users will be converted to use that, thus the datacache vs d handling code can be only contained in stamp_internal() which calls into siggen. Besides, using True/False to replace 1/0 in the patch.

2) When doing populate_sysroot, some la files need to be relocated. 0002 patch changes the relocation handling in destination dirs ("sysroot-destdirs" dirs) instead of source ("image" dirs). This ensures that, contents in "image" directory are not changed and when populating the second machine, the "sed" command can still find those key words.

3) Change emenlow's BASE_PACKAGE_ARCH and PACKAGE_EXTRA_ARCHS to be core2.
