Subject: Serialize access to the info/dir file; needed for parallel installs.

Reported by:	scottl

I'm not very fond of using the non-standard lockf(1) here, but I
have no better idea at the moment.  NetBSD uses ln(1) to create a
lock file, but this approach can result in a deadlock if make is
interrupted, leaving an orphaned lock file.
