Fix malloc_info namespace (bug 17570)
Commit Message
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, fixing one of the bugs shown in the sample output of my proposed
tests for such namespace issues
<https://sourceware.org/ml/libc-alpha/2014-11/msg00157.html>.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).

define as weak alias of __malloc_info.
