If you look in the source you will see that the mode argument of dlopen
is not used at all in the dlopen emulation case, the argument "1" was
not used in the previous version at all. And in fact in the dlopen
emulator case there was no definition for the mode constants at all. I
did change the arguments so the dlopen call can be used in both cases,
with the emulator and with the native dlopen.
