I believe I found the reason of the lost of the symlink
and it is tetex-extra which removed the symlink!

In the tetex-extra.preinst, there was lines;

  if (-l "/usr/share/texmf/doc") {
    unlink "/usr/share/texmf/doc";
  }

so if one installed tetex-extra after tetex-base, then
the symlink was removed, right?
(I don't understand Perl, in fact, but it is easy to
guess the meaning of the above by analogy of sh script ;)

It should be

  if (! -l "/usr/share/texmf/doc") {
    unlink "/usr/share/texmf/doc";
  }

or something similar, shouldn't it?
(Yes, I know it is tetex-preinst.m4 which has really the 
problem.)
