Subject: [PATCH] scripts/recordmcount.pl: remove "-m32" for sh architecture

'allmodconfig' will report error for "-m32", Now "-m32" is useless for
latest compiler and neither can find "-m32" in "arch/sh" directory, so
just remove it is OK.

The related error:

    CC      init/main.o
  sh3-gchen-linux-gnu-gcc: error: unrecognized command line option '-m32'
  sh3-gchen-linux-gnu-ld: cannot find init/.tmp_mc_main.o: No such file or directory
