It depends on the crt0 bits packaged with the sparc64 compiler. I went
through this with riscv64/32 and found the compiler as packaged by
debian couldn't build 32 bit because it wasn't configured to.
Having said that if we are not expecting things to change that much we
could just do it the same way as hexagon. The alternative is to convince
someone to start a estoteric binary distribution that caters to weird
and ancient build tools ;-)
