No. It does not happen for me:

make programs
cp OBJ.linux.x86_64/programs/pluto/pluto .
make clean
make programs
ls -l pluto OBJ.linux.x86_64/programs/pluto/pluto
-rwxrwxr-x 1 paul paul 2617570 2008-08-20 13:12 OBJ.linux.x86_64/programs/pluto/pluto
-rwxrwxr-x 1 paul paul 2617570 2008-08-20 13:11 pluto
