Detect s390x and sparc64 as 32-bit architectures.

CLN fails to build on s390x and sparc64 as it detects them as 32-bit
architectures, due to __s390__ and __sparc__ matching respectively both
s390 and s390x, and both sparc and sparc64. The patch below fixes the
issue. (Reported as Debian bug#639494.)

Thanks to Aurelien Jarno <aurel32@debian.org>.
