[CCC DEV] AVR crossbuild fail on 64 bit

The sources are in Github:
When I did a native build (not a cross build), I configured as follows:
CFLAGS=-fPIC ./configure --with-toolchain=tvm --prefix=<choose target
The build instructions for crossbuild I'm following are here:
and that is failing somewhere that I don't think it should. But, I'm going
to go back and check to see if I have any success on 32-bit before I dig
deeper. I don't want to chase a bug on 64-bit if it exists on 32-bit as
