Multiple copies of makelsr.py

./build/input/regression/out-test/share/lilypond/current/scripts/auxiliar/makelsr.py

I expected the one in scripts/auxiliar, but not the others.  I think they're 
created by this line from make test:

rsync -L -a --exclude 'out-*' --exclude 'out' --exclude mf --exclude 
source --exclude mf /media/IntelSSD/lilypond/lilypond-git/build/out/share 
./out-test
make[1]: Leaving directory 
`/media/IntelSSD/lilypond/lilypond-git/build/input/regression/abc2ly'

but I'm not familiar with rsync.

Does anyone know the intention of the rsync here, and whether we really want 
all the /share directories and files copied to the regression test tree?
