Add mips64 and mips64le support

[tboerger]

As the title say, please add specific files for these architectures. I would do that but I have no idea where we can get the matching maxMapSize and maxAllocSize.

this helped to get it compiling, but idk if these are sane values.

I also have the same issue for misp32 and misple. I fixed the compilation in a similar way as @tboerger did, but I came accross issue #646 (with undefined madvise function) on run.
Sadly, I don't have a clue about what to change to make this work :-/

EDIT, I just noticed that #663 should answer the first part of my issue.
