m32r: make memset() global for CONFIG_KERNEL_BZIP2=y

m32r: make memset() global for CONFIG_KERNEL_BZIP2=y

commit 9a75c6e5240f7edc5955e8da5b94bde6f96070b3 upstream.

Fix the m32r compile error:

  arch/m32r/boot/compressed/misc.c:31:14: error: static declaration of 'memset' follows non-static declaration
  make[5]: *** [arch/m32r/boot/compressed/misc.o] Error 1
  make[4]: *** [arch/m32r/boot/compressed/vmlinux] Error 2

by removing the static keyword.
