I'm probably wrong. OpenBSD sparc64 uses 8k pagesize, too, but doesn't trigger assert.

No idea what that means..

atm sparc64 builds for me, see http://buildbot.rhaalovely.net/builders/mozilla-central-sparc64/builds/399 for a log.

I'm not entirely sure how much sense OpenBSD && Sparc makes, but we can always narrow it later if we hit issues.

sparc64/sparcv9 is in a buildable state, but is broken by design at runtime because of 64-bits jsval (see bug #577056 among others)
