Timestamp of the ar output is truncated after the seconds, if the
current filesystem is of type fuse.encfs.

(see timestamp for hello.a)

I got confused as to why ar was running when it should have been
unnecessary, when running make a second time. The lib looks like it's
older than the object file.

I am not sure if it is an issue with ar or with encfs. The object file
does get a correct timestamp. Please tell me if it's an encfs problem,
and I'll post there.
