+Update OCaml requires/provides to ignore cmxs
+
+OCaml cmxs files are static libraries, which can be loaded at runtime
+via the Dynlink module. They apparently do not provide any useful
+runtime dependency information to be stored into the packages
+Provides/Requires list. Therefore just skip them.
+
+Adjust attr, remove extension and ELF magic
+Adjust ocamldeps, do nothing with cmxs files.
+
+Fixes: a6fe37c39b39acbcbd014dd1e6d5653ff84254a1
