makefiles: make all, clean and distclean PHONY
Avoid a stat() call for each affected target and also potentially speed
up parallel builds.
From the GNU make manual[1]:
> Phony targets are also useful in conjunction with recursive
> invocations of make (see Recursive Use of make). In this situation
> the makefile will often contain a variable which lists a number of
> sub-directories to be built.
[...]
> The implicit rule search (see Implicit Rules) is skipped for .PHONY
> targets. This is why declaring a target as .PHONY is good for
> performance, even if you are not worried about the actual file
> existing.
Commands used to search, replace and cleanup:
$ find -type f -name '*Makefile.in' -exec sed -i.bak \
-e 's/^all:/.PHONY: all\nall:/' \
-e 's/^clean:/.PHONY: clean\nclean:/' \
-e 's/^distclean:/.PHONY: distclean\ndistclean:/' '{}' +
$ find -type f -name '*Makefile.in.bak' -exec rm '{}' +
