I suppose you could do a 

make clean
find . | xargs touch -t 198001010101
make
find . -not atime -1 | xargs rm $i

Which would set all of the access times to be really old, 
rebuild everything, and then remove all files which weren't
touched during the build.

(Be careful; I didn't actually test this command and I wouldn't
trust it too much without testing it, since it's quite capable
of wiping out the whole directory)
