"make report"

I'd like to implement *something* to help us collect information on what
platforms actually have what features. This would be useful, for
example, for figuring out whether any platforms are lacking 8 byte
integers or are missing timezone infrastructure.

I was thinking about something like "make report" which would mail the
results of ./configure to, say, the ports mailing list. We could mention
it in the text message printed at the end of the make cycle.

Comments? Suggestions?
