Steve Langasek agreed.  I am planning to bump the requirement up from
2.2.whatever to 2.4.0 for i486 and powerpc; i486 in order to enable
floating stacks, and powerpc because we've been getting bug reports
that indicate that static binaries are already broken there under 2.2,
and no one wants to debug it.

Any objections before I do this?
