Fix compile errors when using the upstream scripts
Fix compile errors when using the upstream scripts

Not really a fix, just additional ifdefs to use the correct pointer
names for each case.
A proper fix would be to change the names in mupen64 api to fit the
upstream names or vice versa (considering the names I'd suggest the
former)

mupen64plus/mupen64plus-rsp-cxd4,mupen64plus/mupen64plus-rsp-cxd4,mupen64plus/mupen64plus-rsp-cxd4
