If symlink is broken Ada.Directories.Exists returns False (actually it's
because stat64 returns ENOENT in __gnat_stat). 

Easy to reproduce:
mkdir 'test' && cd 'test' && touch target && ln -s target link && rm target &&
cd - && ./del

where del is:
with Ada.Directories;
procedure del is 
begin
  Ada.Directories.Delete_Tree ("test");
end del; 


The problem is even worse if Ada.Direcotiries.Delete_Tree was called and
symlink's target was deleted before the symlink itself.
raised ADA.IO_EXCEPTIONS.USE_ERROR : directory tree rooted at ".uuid" could not
be deleted
