spaces will cause trouble.
Consider using
 join(map(copy(searchdirlist)), 'fnaameescape(v:val)'))
instead

Also 6 lines is bad. Maybe do

, 7)

if len(list) > 6
 throw "something went wrong. file has too many lines"
endif

After modify, tested!

  

function s:Searchwordgl()

  let searchstring = expand("<cword>")

  let searchdir = ''

  for line in readfile("sdir.txt",'',6)

     let searchdir .= fnameescape(line).'*.[csh] '

  endfor

  

  if searchstring != ""

    execute "vimgrep " searchstring searchdir

  endif

endfunction
