At the risk of starting a commit-war, attempt to fix once and for all, the

"make distrib-dirs" target.
Neither of Andrey's two attempts have worked for me with the [ -h ..]
test both with && and ||.
I've changed it to a full
  if [ -h ...]; then \
    rm ... ; \
  fi ; \
construct.  It's much clearer what's meant to happen, and it works! :-)
