shell: Fix build on Solaris 9
Ensure dash can build in a default Solaris 9 or older environment: - Execute scripts with $SHELL rather than /bin/sh, the latter does not support e.g. "if ! .." used by mkbuiltins. - /bin/awk does not support ?: syntax, use explicit statements instead. - /bin/nl requires no spaces between options and arguments.
