[PATCH 2/2] create-spdx-*: Support multilibs via SPDX_MULTILIB_SSTATE_ARCHS

[Mark Hatle <mark.hatle@kernel.crashing.org>]

From: Mark Hatle <mark.hatle@amd.com>

When a create-spdx-* classes is processing documents, it needs to
find the document in a path that is related to the SSTATE_ARCH
when a packge is generated.  The SSTATE_ARCH can be affected by
multilib configurations, resulting is something like armv8a-mlib.

When the image (or SDK) is being generated and the components are
collected, the system has no knowledge of the multilib arch and
will fail to find it, such as:

  ERROR: meta-toolchain-1.0-r0 do_populate_sdk: No SPDX file found
   for package libilp32-libgcc-dbg,
   False sstate:libilp32-libgcc:armv8a-ilp32-mllibilp32-elf:14.1.0:r0:armv8a-ilp32:12:
   sstate:libilp32-libgcc::14.1.0:r0::12:

Adding in the new SPDX_MULTILIB_SSTATE_ARCHS will provide a full
set of SSTATE_ARCHS including ones that contain the multilib
extension which will allow create-spdx-* to correctly find the
document it is looking for.  This would also be valuable to any
other function doing a similar search through SSTATE_ARCH that may
have been extended with multilib configurations.
