Add .PHONY targets to top Makefile for non-file targets
When a make target doesn't result in a file of the same name, adding it
to a .PHONY target means make won't look for such a file, speeding the
build up a bit. This allows `make doxygen' to work since otherwise make
will consider the doxygen directory as up to date.
