h8300: suppress error messages for 'make clean'

'make ARCH=h8300 clean' emits error messages as follows:

  $ make ARCH=h8300 clean
  gcc: error: missing argument to '-Wframe-larger-than='
  gcc: error: unrecognized command line option '-mint32'

You can suppress the second one by setting the correct CROSS_COMPILE=,
but we should not require any compiler for cleaning.
