make: .PHONY lacks .TARGET

[Simon Gerraty <sjg%chaos.jnpr.net@localhost>]

The makefile below:

all ok also.ok bug phony:
        @echo '${.TARGET .PREFIX .IMPSRC:L:@v@$v="${$v}"@}'

.END:   ok also.ok bug

phony bug:      .PHONY
all: phony

produces the following output:

.TARGET="phony" .PREFIX="" .IMPSRC=""
.TARGET="all" .PREFIX="all" .IMPSRC=""
.TARGET="ok" .PREFIX="ok" .IMPSRC=""
.TARGET="also.ok" .PREFIX="also.ok" .IMPSRC=""
.TARGET="" .PREFIX="" .IMPSRC=""

the only difference between the targets phony and bug is that the
later is run via .END, and never gets .TARGET set.
The patch below, seems to be an appropriate fix.
