Info never install

[Artiom Neganov <aneganov@xxxxxxxxxx>]

Hi,

  I'm using emacs-w3m-1.3.6
  When installing via 'make install' it skips "install-info" procedure.
  
  I checked doc/Makefile and found that specifal treatment is performed for
  Debian system:
  

install: $(INFO_DEPS)
        ...
        @if $(SHELL) -c $(INSTALL_INFO)' --version| sed 1q\                                                   
                | fgrep -s -v -i debian'>/dev/null 2>&1; then\                                                
          list='$(INFO_DEPS)';\                                                                               
          for file in $$list; do\                                                                             
            if test -f $(infodir)/$$file; then\                                                               
              echo " $(INSTALL_INFO) --info-dir=$(infodir) $(infodir)/$$file";\                               
              $(INSTALL_INFO) --info-dir=$(infodir) $(infodir)/$$file || :;\                                  
            else : ; fi\                                                                                      
          done;\                                                                                              
        else : ; fi                                                                                           

   But actually, if-condition isn't true for non-Debian systems too
   and for other versions of install-info. After removing if-condition
   files successfuly install into info-tree.

   Sorry, if this is already fixed.
