        for SPU (cell):
        * libc/machine/spu/Makefile.am: Replace printf/scanf family C sources
          to assembler sources.
        * libc/machine/spu/Makefile.in: Regenerated.
        * libc/machine/spu/stdio.c: Add __check_init function wrapping
          CHECK_INIT macro to use from assembler routines.
        * libc/machine/spu/c99ppe.h: Add definitions for assembler code.
