It seems it complains about the first instructions using the 64-bit
registers. My guess is that the assembler is trying to interpret this is
32-bit x86 code. Which won't work at all, of course.
I think you have to first figure out which flags to pass to cc, to get
it to invoke the assembler in x86_64 mode (-m64 is not recognized, and
apparently -xarch=amd64 is not enough). And then we can see how to get
gmp's configure script to do pass the right flags automatically.
