    CONFIGURE: Remove AC_FUNC_MALLOC and AC_FUNC_REALLOC
    
    The AC_FUNC_MALLOC configure check might add the rpl_malloc() entry if it
    does not like the default malloc implementation. The user would need to
    provide the rpl_malloc implementation. This happens depending on compiler and
    OS/distro being used. Same applies for AC_FUNC_REALLOC and rpl_realloc.
    It happened for me when I configured it with address sanitizer (libubsan,
    libasan) activated.
