Sorry for delays, I am travelling. Do we need ".fini_array" section? It's also destructors that we don't run. Or does UML use them? Does discarding ".fini_array" help?libc has desctructors and use them for whatever purpose it needs.Does UML actually gracefully exit running global destructors? That would also require gracefully shutting down all threads/cpus. Doesn't it just _exit (or syscall(SYS_exit_group))?
Sigh, I dunno, I didn't look that far. My intention was to fix build and keep old behavior unaffected. If you want to wipe destructors, and think that this is ok, go ahead.
