[phobos] clock_gettime changes

[Brad Roberts]

I have no problems with the original change, as long as the shipped dmd.conf
file is updated so that it 'just works' for everyone.  The release notes would
need to call this out carefully so that those that maintain their own dmd.conf
file, for whatever reasons, also know about the change.
