Details:

Running "make foo" with a Makefile containing the following two rules
produces different results with make 3.80 and 3.81.

.PHONY: foo

.DEFAULT:
        echo the target is $@

With 3.80, it prints "the target is foo", and with 3.81 it states that
"Nothing to be done for `foo'".   This was caused by adding the following
line to file.c in int .PHONY case (line 675).

          f2->is_target = 1;

This is a regression, since it breaks our makefiles, and I don't understand
why phonies should be considered as explicit targets unless there are actual
rules for them.

The ChangeLog mentions this, but it doesn't really explain why the change was
made.

        * file.c (snap_deps): Mark .PHONY prerequisites as targets.

        * implicit.c (pattern_search): When considering an implicit rule's
        prerequisite check that it is actually a target rather then
        just an entry in the file hashtable.
