I just proved my theory wrong by doing the following:

$ sudo chown /obj /wnw
$ sudo chown ngie /obj
$ env MAKEOBJDIRPREFIX=/obj NO_CLEAN=1 script /tmp/bw make buildworld -j4
$ sudo make installworld DESTDIR=/wnw
$ sudo chroot /wnw /bin/sh
# cat <<EOF > hello_world.c
#include <stdio.h>
int main(void) {
printf("hello world\n”);
return 0;
# cc -o hello_world hello_world.c
# ./hello_world
hello world

I did however prove that there’s a bug still in the tests by doing what I did above:

# kyua report

Working on a fix right now.
