[PATCH 0/4] Implement multilib SDK support

[Mark Hatle <mark.hatle@windriver.com>]

The attached patch set implements multilib SDK support.  This means that 
when generating an SDK (either by a traditional SDK recipe or the
do_populate_sdk task), that support infrastructure for each multilib
will be included in the SDK.

Note, this code does -not- change the toolchain.  If the generated toolchain
does not work properly with the multilib configuration, that will need to
be a seperate fix!

This was tested with both the oe-core and our custom Wind River toolchain.
Generation passed on the oe-core SDK, but the functionality of the toolchain
was not tested.  The Wind River toolchain did get properly generated and
functioned as expected.

Note:  The 0003 patch that affects processing the environment file was
agreed to with the other author of the function.

The following changes since commit 06d27cf0fbcc4004e6f456880eca49893c9290bf:
