The systags.sh script suffers from some minor bit-rot.
Fix: Context diffs to conf/systags.sh and i386/conf/Makefile.i386
RCS file: RCS/systags.sh,v
retrieving revision 1.1
For example, it uses "machine" (doesn't exist) and "egrep -o"
(no such flag).
Also, the "tags" target for the i386 Makefile says:
@echo "see $S/kern/Makefile for tags"
when it should just invoke systags.sh directly
Duplicate of PR#2806 which was just closed (in both branches).
