Hi Guys,

  Right - I have applied a patch (also uploaded to this PR) which adds 3 new
  warnings to the linker:

warning: <obj>: requires executable stack (because the .note.GNU-stack section
is executable)

warning: <obj>: missing .note.GNU-stack section implies executable stack

warning: enabling an executable stack because of -z execstack command line
option

  The first two are enabled by default, but the third one is only generated
  if the new --warn-execstack command line option is used.  The first two
  can also be suppressed by using the --no-warn-execstack option.

  The wording and option names were chosen to be similar to the ones used/
  generated by the GOLD linker.  (Although GOLD does not generate the third
  type of warning message).

Cheers
  Nick
