>Description:
I have read-only src null-mounted, which may be the issue, but the recent 
changes to ls break my build
        
>How-To-Repeat:
usr/src/build.sh -O /usr/obj/amd64 -T /usr/obj/tools.amd64 -U -r -x -m amd64 
-j9 release iso-image

Fails with:
===> build.sh command:    /usr/src/build.sh -O /usr/obj/amd64 -T 
/usr/obj/tools.amd64 -U -r -x -m amd64 -j9 release iso-image
===> build.sh started:    Fri Feb 21 22:49:59 PST 2014

>Fix:
in /usr/src/bin/ls, cvs update -D 20140214, install that, and try again
