On Debian 9 / sparc64: * In 64-bit mode, all tests pass.
* In 32-bit mode (CC="gcc -m32"):
- test-readutmp fails, because all timestamps are from 1970-01-01,
- 'src/who' does not produce any output.
Here, readutmp is based on glibc's "getuxtent".
I'm not investigating further, since Debian/sparc64 is no longer supported.
