* the staticlibext for i8086-msdos changed from .lib to .a; rationale:
  1) less special cases needed in fpmkunit for i8086-msdos
  2) consistency with the naming scheme on the go32v2 target
  3) we didn't follow the DOS naming scheme completely anyway, e.g. we used .o
     for object files, instead of .obj
