VOL-4840 - gendocs edits

Makefile
--------
   o Display an ENTER/LEAVE banner & whitespace for readability.
   o Changed ${} to $() to make it clear these are make vars not env vars.
   o mkdir one-liner: use make builtin $(addprefix) to construct paths,
     spawn one shell -vs- shell mkdir x dirs.
   o Join shell commands using '&&' -vs- ';'.  Ssemicolon use with
     line continuation can mask failures.
