No.  I changed "TOP=$(pwd)" to "TOP=$(/bin/pwd)" as I showed

That's true.  Therefore, I used /bin/pwd.

Anyway, I ran "./build.sh -U -O /usr/obj release" with
modified build.sh.  It finished fine.  All binaries are
stored in /usr/obj/{bin,lib,usr.bin,...} although I'm using
a symbolic link to refer source trees (like automount does).
