>Description:
cross-building netbsd5 on current-amd64 is missing /var/db/libc.tags and says:

======  1 missing files in DESTDIR  ========
Files in flist but missing from DESTDIR.
File wasn't installed ?
------------------------------------------
./var/db/libc.tags
========  end of 1 missing files  ==========
        
>How-To-Repeat:
netbsd-5 is checked out into /usr/stable/src and /usr/stable/xsrc. The build 
script is:

#!/bin/sh
cd /usr/stable/src && \
/usr/stable/src/build.sh -j8 -m amd64 -T /usr/cross/amd64-stable -O 
/usr/obj/stable/amd64 -X /usr/stable/xsrc -U -u obj tools && \
/usr/stable/src/build.sh -j8 -m amd64 -T /usr/cross/amd64-stable -O 
/usr/obj/stable/amd64 -X /usr/stable/xsrc -U -u distribution release iso-image 
&& \
#/usr/src/build.sh -j8 -m amd64 -T /usr/cross/amd64-stable -M /usr/obj/stable 
-U -u kernel= GENERIC && \
/usr/stable/src/build.sh -j8 -m sparc64 -T /usr/cross/sparc64-stable -O 
/usr/obj/stable/sparc64 -X /usr/stable/xsrc -U -u obj tools && \
/usr/stable/src/build.sh -j8 -m sparc64 -T /usr/cross/sparc64-stable -O 
/usr/obj/stable/sparc64 -X /usr/stable/xsrc -U -u distribution release 
iso-image && \
/usr/stable/src/build.sh -j8 -m sparc64 -T /usr/cross/sparc64 -u kernel=EMILY
>Fix:
        
        Just "touch"-ing the file allows the build to complete.
