Undesirable bmake behavior

[Alexander Kabaev]

Hi,

today I got confronted with this little curiosity from bmake. I have
built and installed the world, and after reboot I ran 'make delete-old'
as root to get rid of accumulated stale files. This is what I got back:

>>> Removing old files (only deletes safe to delete libs)
....
>>> Old files removed
>>> Removing old directories
>>> Old directories removed
To remove old libraries run '/usr/obj/usr/src/make.amd64/make
delete-old-libs'.

It turns out that somehow running make in src tree finds and tries to
run a copy from .OBJDIR, if one is present, unconditionally now. I do
not think this that is a particularly desirable and even sane behaviour
- once buildworld has finished, no tool should ever try to run
_anything_ from what is essentially a scratch space. Bootstrap and
cross tools should only be used during corresponding stages of
buildworld and by default.
