clean/distclean speedup

[Paul Fox]

i know these targets aren't used _that_ often, but if we're
allowed to use xargs, this patch makes 'make clean' and 'make
distclean' somewhat faster.  i won't apply this myself -- i'll
leave it to someone who feels more responsibility for the
makefiles than i'm willing to take.  ;-)
