>Description:

        The do-sys-modules target in the top-level Makefile is gone, so
        `build.sh modules' no longer works.

        If I try making dependall and install in sys/modules manually,
        then I see the following failure:

#   install  
/home/riastradh/netbsd/current/src/../obj.amd64/destdir.amd64/usr/libdata/ldscripts/kmodule
/home/riastradh/netbsd/current/src/../tools.amd64/bin/x86_64--netbsd-install -U 
-M /home/riastradh/netbsd/current/src/../obj.amd64/destdir.amd64/METALOG -D 
/home/riastradh/netbsd/current/src/../obj.amd64/destdir.amd64 -h sha256 -N 
/home/riastradh/netbsd/current/src/etc -c -p -r  -o root  -g wheel  -m 444   
kmodule 
/home/riastradh/netbsd/current/src/../obj.amd64/destdir.amd64/usr/libdata/ldscripts/kmodule
 
x86_64--netbsd-install: 
/home/riastradh/netbsd/current/src/../obj.amd64/destdir.amd64/usr/libdata/ldscripts:
 mkstemp: No such file or directory
*** 
[/home/riastradh/netbsd/current/src/../obj.amd64/destdir.amd64/usr/libdata/ldscripts/kmodule]
 Error code 1

>How-To-Repeat:

        Attempt `build.sh modules'.  Failing that, attempt
        `nbmake-amd64 dependall && nbmake-amd64 install' in sys/modules
        manually.

>Fix:

        Yes, please!
