[PATCH] Fix malloc_usable_size definition

[mh+jemalloc at glandium.org]

From: Mike Hommey <mh at glandium.org>

The function declaration in system headers uses void * instead of const void *, and
that can lead to conflicts when building against recent Android NDKs, where string.h
includes malloc.h, which contains that conflicting definition.
