Patch to build 64 bit VM

[Michael Franz]

Greg,

This is my output:
Apple Inc version cctools-698.1~1, GNU assembler version 1.38

I have been trying to build 64 bit by only passing in the LP64=1 .  I have
not been able to get it to work, it gets pretty far.  I have to change some
cast from int64_t to intprt_t to get as far as I do.

Once I put in the correct casts (change int32_t to intptr_t) the 32 bit
build is fine.

I have not imported your latest commits.

Michael
