Previously ar and ranlib did not produce an error exit status in the case of a misisng file etc.

Bring over the error handling added by ELF Tool Chain after forking FreeBSD's ar.

markj added inline comments.

usr.bin/ar/acpyacc.y
194	Looks like this is just a related cleanup? There is a similar change in acplex.l that is not included here, EX_SOFTWARE -> EXIT_FAILURE.
662	There are quite a few more sysexits.h removals in upstream ar, not sure if the intent was to port them all?
usr.bin/ar/ar.c
282	EXIT_FAILURE here too? Or should we go further and eliminate the exit status parameter from bsdar_errc() and hard-code EXIT_FAILURE, like elftoolchain did?
350	None of these calls are checked?

emaste added inline comments.Aug 4 2021, 3:34 AM

usr.bin/ar/acpyacc.y
194	Right, I just compared usr.bin/ar with elftc files and updated exit status related parts (that I found) to match elftc. acpyacc.y could indeed be left unchanged, but I think converging on elftc is preferable.
662	Not a bad idea, perhaps a second pass.

Improvements from @markj

LGTM aside from the one comment.

usr.bin/ar/read.c
163	Upstream ar returns EXIT_FAILURE in this case (`r == ARCHIVE_FATAL` check at the end of ar_read_archive()).
