I haven't set anything explicitely in the environment, the relevant
(.ifndef BSD_PKG_MK and outside) mk.conf entries boil down to:

TOOLDIR=/usr/tools
USE_INET6=NO
MKOBJDIRS=yes

.ifndef BSD_PKG_MK
USE_XF86_4=yes
.else
# ...
.endif

Ah, I see, thank you for the explanation.

I found it in /space/obj/usr/src/tools/PREVIOUSTOOLDIR, containing 
"/usr/tools". I'm not sure if it's from the `tools' build or from
the `distribution' rebuilding it, given the (m)time of it, I'd assume
the latter.

Thanks for your time,
