[PATCH] m32r: Fix ELF_CORE_COPY_REGS macro to generate a correct "core" file

This patch fixes ELF_CORE_COPY_REGS() macro in order to dump register
information into "core" files correctly, because both parameters pr_reg and
regs are passed as pointers to "elf_gregset_t" and "struct pt_regs",
respectively.

I've tested it by using a native m32r GNU debugger.
