#69599: hardcode-m4.patch seems to introduce a minor issue
-------------------------+---------------------
 Reporter:  TurtleWilly  |      Owner:  (none)
     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:
 Keywords:               |       Port:  libtool
-------------------------+---------------------
 In the "hardcode-m4.patch" it does this:

 {{{
 +# GNU M4.
 +M4=$lt_M4$
 +
 }}}


 In the resulting libtool it generated this:

 {{{
 # GNU M4.
 M4="/usr/local/bin/m4"$
 }}}

 The trailing dollar sign looks a bit out-of-place and unnecessary, albeit
 it doesn't seem to do any harm.
