More weirdness...

I decided to rebuild; this failed with
===> Build platform:      NetBSD 6.99.4 amd64
===> HOST_SH:             /bin/sh
===> TOOLDIR path:        /usr/obj/auto-current/tools

./build.sh: /usr/obj/auto-current/tools/bin/nbmake-amd64: permission denied

ERROR: Failed to make release
*** BUILD ABORTED ***
...

and indeed

 # ls -l /usr/obj/auto-current/tools/bin/nbmake-amd64
-rw-r--r--  1 root  wheel  1304 Mar 21 09:52
/usr/obj/auto-current/tools/bin/nbmake-amd64

but then:

root@support6 /devi # ls -l /usr/obj/auto-current/tools/bin/nbmake-amd64
-rw-r--r--  1 root  wheel  1304 Mar 21 09:52
/usr/obj/auto-current/tools/bin/nbmake-amd64

root@support6 /devi # ls -l /usr/obj/auto-current/tools/bin/nbmake-amd64
-rw-r--r--  1 root  wheel  1304 Mar 21 09:52
/usr/obj/auto-current/tools/bin/nbmake-amd64
root@support6 /devi # which chmod
/bin/chmod
root@support6 /devi # ls -l /bin/chmod
-r-xr-xr-x  1 root  wheel  11682 Mar 20 23:16 /bin/chmod*


No idea what is going on.
