bug#69908: dist-no-built-sources vs. no-dist-built-sources vs. dist-built-sources

Hi,

I just realized the last part might be confusing.

What I meant by "looks identical" is only the output of the *second* 
grep (see linked script), not the whole file:

    BUILT_SOURCES = x.c
    all: $(BUILT_SOURCES)
    distdir: $(BUILT_SOURCES)
    check: $(BUILT_SOURCES)
    install: $(BUILT_SOURCES)
    install-exec: $(BUILT_SOURCES)
        -$(am__rm_f) $(BUILT_SOURCES)

Have fun,

JensG
