    Fix malloc_info namespace (bug 17570).
    
    malloc_info is defined in the same file as malloc and free, but is not
    an ISO C function, so should be a weak symbol.  This patch makes it
    so.
    
    Tested for x86_64 (testsuite, and that disassembly of installed shared
    libraries is unchanged by the patch).
    
            [BZ #17570]
            * malloc/malloc.c (malloc_info): Rename to __malloc_info and
            define as weak alias of __malloc_info.
