x86_64, I guess.

It's usually configure, make, make install.  Debian-derived distros
have some patches because they put 64-bit libraries in /lib instead of
/lib64, which is where the standard says they should be.  I don't
think you'll have any such problems with SUSE, though.

Maybe someone who has built Debian on x86_64 can respond.
