* instruby.rb, ext/extmk.rb, Makefile.in, win32/Makefile.sub,

  bcc32/Makefile.sub: Replace the complicated MFLAGS/MAKEFLAGS
  parser with something plain and comprehensible.  This fixes a
  bug where make flags were wrongly reordered and the resulted
  command line often did not make sense especially when BSD make
  is used with extra arguments given.  Tested with FreeBSD and
  Linux by me and mswin32, bccwin32 and mingw by usa.
