You don't use SSH?

i.e., on certain architectures, notably SPARC, OpenSSL benefits
*massively* from being built for v8 and above, because of v7's lack of
integer multiply instructions; we're talking SSH connections being
established ten to fifty times faster with v8 optimizations in
OpenSSL. These days most distros have recognised this, and the
multi-arch support in glibc permits you to ship multiple OpenSSLs in
appropriate directories and have them picked up by the appropriate
machines, but before that, you pretty much *had* to build OpenSSL
from source if you wanted a usable SSH.

There are still some cases like that.
