i did not do a full migration as i got bored, but i did do enough to show
it in action.  the current method does not require all be converted at the
same time though, so it can be left up to maintainers of relevant packages
to do the change over themselves.

the patchset allows for some targets (notably Linux systems) to control
whether the flag is enabled.  it is turned off by default and i think
that's the behavior we want.  i have not forced enabled it for any target
but maybe the prefix/darwin guys will want to do that.
