            Bug ID: 191054
           Summary: make clean/cleanobj does not clean as expected with
                    bsd.progs.mk
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: Needs Triage
          Severity: Affects Only Me
          Priority: ---
         Component: misc
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: yaneurabeya@gmail.com

When trying to isolate some issues with bsd.test.mk, I noticed that make
clean/cleanobj  was not cleaning as expected, in particular make clean does not
clean any of the compiled programs, and make cleanobj only cleans out the last
compiled program. If I run make cleandir, it napalms the heck out of the
directory by deleting the bsd.dep.mk files 6 times (twice for cleandir, twice
for cleanobj, twice for cleandepend) and the generated objects 2 times each
(once each for cleanobj, once each for cleandir).

I've provided an example below:

% uname -a
FreeBSD isilon-fuji-current.local 11.0-CURRENT FreeBSD 11.0-CURRENT #5
0d2be6b(isilon-atf): Sun Jun  8 21:34:32 PDT 2014    
root@fuji-current.local:/usr/obj/usr/src/sys/FUJI  i386
% cat *
# Makefile

MAN=

.include <bsd.progs.mk>
/* a.c */
#include <stdio.h>

int
main(void)
{

    printf("hello world!\n");
    return (0);
}
/* b.c */
#include <stdio.h>

int
main(void)
{

    printf("hello world!\n");
    return (0);
}
/* c */
This directory contains a simple C app that says, "hello world!"

Expected behavior:

- make clean should clean all apps and generated files.
- make cleanobj should just nuke ${.OBJDIR}; it shouldn't have to nuke the
files under ${.OBJDIR} (bsd.obj.mk ensures that requirement is met for
cleanobj).
- make cleandir should does the same thing as cleanobj (why they're separate
targets, I have no idea, but cleanobj isn't advertised in the docs though...).
