Update error message for non-PE format output files

[Nick Clifton]

Hi Guys,

  Whilst investigating PR 2757 I found that the error message we emit
  when we are asked to generate a non PE format output file from PE
  format input files is rather cryptic.  So I am applying the patch
  below to make it slightly more helpful.

Cheers
  Nick
