.PHONY is a special target in a makefile that tells make "hey, rebuild
this target no matter if there's a file of the same name or not"

It appears as though the DGUX make wasn't up to the task for some
reason. Similar observations apply to hold Solaris 8's
/usr/ccs/bin/make which chokes on src/Makefile here. BSD make fares a
bit better, it "only loses some dependencies" causing excessive rebuilds
during development work, but it's fine for a first-time build.

GNU make is fine, well-tested and I'd recommend using GNU make when your
system's make variant causes trouble. There isn't much we can do about
how the Makefile.am generated targets look like.
