[OE-core] [CONSOLIDATED PULL 09/17] populate_sdk: enable basic multilib support

From: Mark Hatle <mark.hatle at windriver.com>
In order to enable basic multilib support for the export of an SDK
image, a number of minor changes had to be made:
The value of MULTIMACH_TARGET_SYS needs to be variable. This way we
can define the value to the appropriate multilib. (Also in some cases
the default PACKAGE_ARCH is set to MACHINE_ARCH which is incorrect for
the SDK.) Add a companion REAL_MULTIMACH_TARGET_SYS, based on code
from meta-environment, to allow for this.
We have to convert the do_populate_sdk into a python call, and then
break up the previous items into three parts.
* Image construction
* Setup of environment files
* Generation of the tarball
Then we can iterate over the multilibs to populate the environment files.
Finally, matching changes were needed in the toolchain-scripts file. And
what I presume is an optimization of immediate evaluation for
TOOLCHAIN_CONFIGSITE_NOCACHE and ..._SYSROOTCACHE needed to be done at
runtime, otherwise the wrong values may be used.
