Right, it was the default setting in GAR for 5.9: to build sparcv8
binaries. There was a time your packages would be rejected if you built
binaries for sparcv8+.  This policy is now gone, and you can build and
release sparcv8+ binaries.

We had a similar rule to build for 386, where 386 didn't stand for just
Intel processors, it actually meant the 386 processor, as opposed to the
newer 486.
