Add more sysctls.

Changed commit message.

@phil for a confirmation as well.

We can probably just do this all the time without needing the flag? I think kldxref just doesn't care, or more likely ef_object.c in kldxref wasn't updated when the kernel linker changed.

Addresses jhb@'s comments

Updated to adapt to NOSAN's introduction

Comments update.

Oops.

Fix per markj@'s comment. ef_print_phdr related part now is left unchanged for now.

Bootstrap it everytime, and remove the __FreeBSD_version bump as well given this library is private.

Remove include headers installation

Update commit message. If it is not reflected on Phabricator I will do it one more time.

This is missing some description of libkldelf's intended functionality, either in the commit message or in a man page (maybe a man page is not required for private libraries). It's hard to tell at a glance what this library does, at least for me who is not familiar with kldxref internals.

I don't have any objection to the change itself, it seems fine and will be useful for debuggers and related tools. libdtrace might be able to take advantage of it as well, replacing some existing code.

Update Makefile.depend as well.

Fix indentiation issue in mtree files

Do we need ef_mips.c still ?

Updated to be a private library.

I think I have to make it PRIVATELIB to be more useful.

Superseded by D46719.

per jhb@'s suggestion.
