Okay, it's not just yacc. All the /usr/bin CLT stubs seem to have the 
same inode. Is anything else missing? This'll tell us:

    #!/bin/sh

    inode=$(ls -li /usr/bin/yacc | awk '{print $1}')
    stubs=$(ls -li /usr/bin | grep ${inode} | sed -e 's|.* ||')

    for i in ${stubs}; do
    	/usr/bin/xcrun --find $i >/dev/null 2>&1 || echo $i
    done

Output:

    llvm-g++
    llvm-gcc
    m4
    yacc

So we'll have to defend against m4 that's not really there, too.
