You could build only cc1 and use gcc -v with a native compiler to see
what kinds of options to give your cc1 to compile a source file to a .s
file.  The basic procedure for building cc1 is:

  cd $objdir
  $srcdir/configure --enable-languages=c $other_configure_options
  make all-libiberty
  make configure-gcc
  cd gcc
  make cc1
