All modern SPARC systems are 64-bit. The Sun Ultra 1, which was the first
64-bit machine from Sun, was bought out in 1995 - i.e. 15 years ago, well
before any Intel or AMD chip was 64-bit.
However, to maintain backward compatibility, and to increase performance,
Sun chose to retain the default builds as 32-bit. So are in fact building
Sage 32-bit on Solaris, though a 64-bit build is possible.
The fact John said the tests fail on 'mark' but pass on 'fulvia' does
indicate it's very likely to be a big-endian issue. I have a machine
running HP-UX which uses a PA-RISC processor. That is big-endian. I could
try building Pari on there, though I'm not sure if it will work or not.
I'd not be surprised if it failed to build on there.
