>Description:

Without a /etc/mk.conf, run "./build.sh -U distribution" on a clean /usr/src 
then run "./build.sh -U install=/" and see a bit of confusion over where 
DESTDIR, TOOLDIR and so on are.

On the second run /usr/src/obj exists. On the first run it doesn't.

>How-To-Repeat:

You can see the problem by focusing on build.sh as here:

frodo% sh chris.sh 
SRCTOP: /usr/src
TOOLDIR: /usr/src/tooldir.NetBSD-4.99.40-i386
frodo% ln -s /usr/obj .
frodo% sh chris.sh
SRCTOP: /usr/src/obj
TOOLDIR: /usr/src/obj/tooldir.NetBSD-4.99.40-i386

where chris.sh is a snippet of build.sh
#!/bin/sh
make=/usr/bin/make

nobomb_getmakevar()
{
        [ -x "${make}" ] || return 1
        "${make}" -m share/mk -s -B -f- _x_ <<EOF || return 1
_x_:
        echo \${$1}
.include <bsd.prog.mk>
.include <bsd.kernobj.mk>
EOF
}

_SRC_TOP_OBJ_=$(nobomb_getmakevar _SRC_TOP_OBJ_)
TOOLDIR=$(nobomb_getmakevar TOOLDIR)
echo "SRCTOP: $_SRC_TOP_OBJ_"
echo "TOOLDIR: $TOOLDIR"

>Fix:
	Ensure that /usr/src/obj exists correctly earlier in build.sh.
