Distgen does different stuff when called several times about container-common-scripts HOT 1 CLOSED

GNU make by default doesn't check for symbolic link timestamps (see option
-L that would help).

1. We can make the output nicer, always executing the LN but not printing
   it to stdout to not confuse people. I'd suggest to do some "check"
   that the symlink points to where it should point to (read the link
   manually, and compare) and regenerate it only when needed.

2. We can force make -L execution, but that has drawbacks, per docs:

'-L'
'--check-symlink-times'
     On systems that support symbolic links, this option causes 'make'
     to consider the timestamps on any symbolic links in addition to the
     timestamp on the file referenced by those links.  When this option
     is provided, the most recent timestamp among the file and the
     symbolic links is taken as the modification time for this target
     file.

3. We can backup each symlink by some other file (dot-file) in some
   working directory, and do the symlink creation only if the file itself
   has outdated timestamp.
