lib/util.sh: make (): don't change the directory to $top_dir, because paths used by the caller will instead be relative to the current dir (note that in runscripts, paths are generally not absolute because of canon_rel_path ()). this requires manually specifying $top_dir when running make on a physical (rather than inlined) makefile.

lib/util.sh: log_stderr_cmd (): replaced the `|| exit` after the () with `|| return`, for the same reason that this was a problem for extern () (see r8954)

lib/util.sh: extern (): replaced the `|| exit` after the () with `|| return`, because `|| exit` strangely does not use $? as its exit status (even though `|| exit $?` works fine). in a shell function, it is actually sufficient, for errexit purposes, to use `|| return`, because the exit status is checked upon return from the function. it is in fact preferable to use return rather than exit, because then the caller can catch the exception using `|| true`.

lib/util.sh: extern (): removed the `|| exit` inside the (), because this strangely prevents the exit status from being propagated to the exit status of the ()

lib/util.sh: added explicit `set -o errexit` in case caller did not have -e in #! line
