    configure: Don't try to enable the log2 function on msvcrt · 88a35699

    Some msvcrt versions (the static 64 bit libc in MSVC 10) have
    a log2 function, but there is no declaration for it in the headers.
    Therefore, the normal configure check might find it, but it can fail
    during build or at runtime, depending on whether implicit function
    declarations are an error or not.
    
    Therefore simply ignore this function on this platform.
