compile directory is not under /usr/src/sys (i.e. when 'S' is not '../../../..'). Pointed out by Robert Elz in PR 17384. Thanks again to Andrew Brown for figuring out how to rip .depend apart.

# This file contains common `MI' targets and definitions and it is included
|
|
# at the bottom of each `MD' ${MACHINE}/conf/Makefile.${MACHINE}. There are
|
|
# many `MI' definitions that should end up in here, but they are not yet.
|
|
#
|
|
# Each target in this file should be protected with `if !target(target)'
|
|
# or `if !commands(target)' and each variable should only be conditionally
|
|
# assigned `VAR ?= VALUE', so that everything can be overriden.
|
|
#
|
|
# DEBUG is set to -g if debugging.
|
|
# PROF is set to -pg if profiling.
|
|
#
|
|
# To specify debugging, add the config line: makeoptions DEBUG="-g"
|
|
# A better way is to specify -g only for a few files.
