Makefile: Fix "make clean" in "unconfigured" source directory

Browse Source 
Recent commit "Makefile: Reuse all's recursion machinery for clean and
install" broke targets clean and distclean in the source directory
before running configure:

    $ make clean
      LD      recurse-clean.mo
    cc: fatal error: no input files
    compilation terminated.
    make: *** [rules.mak:118: recurse-clean.mo] Error 1

Root cause is missing .PHONY.  Fix that.
