[PATCH v2 0/7] objtool/klp: sympos/module/alternative/etc fixes

[Josh Poimboeuf <jpoimboe@kernel.org>]

v2: 
- rebased on tip/master (first 6 patches were merged)
- dropped original patches 7-8 (will post followup)
- added .klp.symid fix

v1: https://lore.kernel.org/cover.1785727106.git.jpoimboe@kernel.org

This consolidates fixes for the klp-build issues reported by Joe over
the last several weeks, plus some more things I found while
testing/reviewing.

Fun stuff like symbol resolution, module dependencies, alternatives.
