OK. Here's a revised patch. It doesn't touch the configure system, and it 
doesn't introduce a new option. You can do --atime-preserve, 
--atime-preserve=replace, or --atime-preserve=system. If O_NOATIME isn't 
defined at compile time, --atime-preserve=system will generate a usage error 
message.

I wasn't sure about the right way to document the --atime-preserve option. 
Right now I define the argument as "replace|=system", so that --help shows 
--atime-preserve[=replace|=system]. But this strikes me as a hack. Let me 
know if you have a better idea.
