[CCC DEV] AVR crossbuild fail on 64 bit

As far as I'm concerned, our project doesn't work.
1. I don't think a TVM build on a 64-bit machine works. Even with -fPIC,
the tvm segfaults out on most tests. I may have done something wrong,
2. A cross-build fails, implying to me that something in the chain is
broken. I don't know if that is a compiler oddity, or something simpler and

I'll try and trace it down, but (as usual) I'm trying to get things working
so I can do work, now, with students. (Invariably, I'm never doing this in
a reasonable way, months in advance, because I don't think life works that
My solution is going to be to set up a 32-bit VM, and hope that I can do a
clean build there. I'm simply reporting that I am pursuing what I hope will
be a faster path to a working system.
If anyone gets bored, and wants to try and help me get a working build on
64-bit platforms, that would be great. A "working build" means "we can run
kroc, the TVM, and do an Arduino cross-build."
