This is something of a hack also but you could create a separate layer
just for displaying the legend. Remove the NAME from your CLASS  above
to prevent it from displaying in the legend.

Create a new LAYER:
NAME Cerclestt_legend
STATUS DEFAULT
TYPE POINT
CLASS
  NAME "Symbole cercle TT"
  COLOR 255 0 0
  # circle name defined in symbol.sym file
  SYMBOL "circle"  
  SIZE N
END

Set N to the size you want in pixels.  You could also create a TrueType
"N" circle in your symbol.sym file and use that as your SYMBOL.
