Bug#775611: [sh]: FTBFS due to unknown compiler option '-m32'

Hi!

The kernel package currently fails to build from source on sh4 since
the build scripts try to pass the '-m32' compiler option on gcc which
is not available with gcc on sh4 (also according to the manpage).

Selecting HAVE_C_RECORDMCOUNT in arch/sh/Kconfig (see attached patch
by Ben Hutchings) fixes the issues. However, I also suggest removing
the line "$cc .= " -m32";" for sh compiler options in scripts/
recordmcount.pl.

Thanks!
Adrian
