    malloc: Simplify static malloc interposition [BZ #20432]

    Existing interposed mallocs do not define the glibc-internal
    fork callbacks (and they should not), so statically interposed
    mallocs lead to link failures because the strong reference from
    fork pulls in glibc's malloc, resulting in multiple definitions
    of malloc-related symbols.

    (cherry picked from commit ef4f97648dc95849e417dd3e6328165de4c22185)

    malloc: Run tests without calling mallopt [BZ #19469]

    The compiled tests no longer refer to the mallopt symbol
    from their main functions.  (Some tests still call mallopt
    explicitly, which is fine.)

    (cherry picked from commit f690b56979dea81340a397c1b5e44827a6fb06e7)
