Ah, of course.  So for a quick fix, you could revert just the changes
to lib/Kconfig and all the defconfigs.  That way all the UNUSED_SYMBOLS
infrastructure is still removed, but TRIM_UNUSED_KSYMS remains (un)set
whenever it used to be (un)set and that could then be cleaned up in a
followup patch set per architecture when we know it works.
