Jordan K. Hubbard cd9a2f5c28 Bring in my changes for removing the pestilent obj links (unless you
really want them) from /usr/src.  This is the final version of the
patches, incorporating the feedback I've received from -current.

#
# The include file <bsd.obj.mk> handles creating 'obj' directory
# and cleaning up object files, log files etc.
#
#
# +++ variables +++
#
# CLEANFILES Additional files to remove for the clean and cleandir targets.
#
# MAKEOBJDIR Specify somewhere other than /usr/obj to root the object
# tree. Note: MAKEOBJDIR is an *enviroment* variable
# and does work proper only if set as enviroment variable,
# not as global or command line variable! [obj]
#
# E.g. use `env MAKEOBJDIR=/somewhere/obj make'
#
# NOOBJ Do not create build directory in object tree.
#
# OBJLINK Create a symbolic link from ${.TARGETOBJDIR} to ${.CURDIR}/obj
# Note: This BREAKS the read-only src tree rule!
#
# +++ targets +++
#
# clean:
# remove a.out Errs errs mklog ${CLEANFILES}
#
# cleandir:
# remove the build directory (and all its contents) created by obj
#
# obj:
# create build directory.
