If the user passes

./configure --with-runhelpdir=/prefix/usr/share/zsh/5.0.2/help

then $runhelpdir will not be "yes", but runhelp should
be defined anyway. Probably you want instead something like

if test x"$runhelpdir" = xyes; then
  runhelpdir=${datadir}/${tzsh_name}/'${VERSION}'/help
fi
if test x"$runhelpdir" = ""; then
  runhelp=runhelp
else
  runhelp=
fi
