use the magic macros in mips.cpp, change signature of stuff in floppy.h to hint that it needs an array, not just a pointer, although it doesn't actually warn if you just give a pointer anyway (nw)

// This happens to work by chance if the next poitner-sized piece of BSS data happens to be zero, which it is most of the time.
// However, for some reason on a Linux clang 6 build it sometimes isn't, causing a lovely crash here.
// If this is supposed to be a nullptr-terminated array of function pointers, the code needs to be changed to better enforce it.
