note that we do not want hidden malloc aliases

We want to let malloc() and friends be overridable at runtime so that apps
can insert their own implementation (think debugging, specialized setups,
etc...).  That means that C library functions that return allocated memory
have to go through the normal malloc() symbol as well as the external code
is the one who will be calling free().
