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.
