[PATCH] maint: use $(AM_V_GEN) to cut down on build noise

[Jim Meyering]

FYI, I noticed a little too much output scrolling by with
each "make" command, e.g.,

    for po in `ls -1 ./*.pt_BR.po 2>/dev/null`; do \
            make $(basename ${po%.pt_BR.po}); \
    done
    make[4]: Entering directory `/h/j/w/co/parted/6/doc/pt_BR'
    for locale in pt_BR ; do \
            po4a-translate -f man -m ./../C/partprobe.8 -p 
partprobe.8.$locale.po -l partprobe.8  ; \
            if [ -f ./partprobe.8.$locale.po.addendum ]; then \
                    po4a-translate -f man -m ./../C/partprobe.8 -p 
partprobe.8.$locale.po -l partprobe.8 -a ./partprobe.8.$locale.po.addendum  ; \
            fi ; \
    done

so made the following change.
Now, in place of the above, I see only one line:

    GEN      partprobe.8

You can still see the gory detail by building with "make V=1".
