We need the capability to specify at build time (archive creation time) extra
DSP-side libraries that are not part of the C6Run backend libraries. Suggested
mechanism would be to use a -l option in the archiver. Also, all object files
that are brought into the archiver call that do not have the required hidden
components (the stubs and fxn list files) should just be passed directly to the
c6lx linking step.
