apologies for the multiple versions here. Please disregard v2.
The v3 patch (as seen below) is the right one to use, as it handles
--disable-build-timestamp appropriately.
I find that trying to get it to pass "[none]" through all the autotools
business ends up turning into "none", so i went with "<none>" instead,
which shouldn't be mistaken for an ISO-8601 date format.
