            This is suspicious. Are you able to execute "yacc --version"
            In newer versions of Bison, yacc is not a symlink, but readlink
            should return an empty string in that case.

I don't know the command to execute. I use LFS 7.6

yacc --version

The result should be the same as 'bison --version'

In some cases yacc is just a wrapper script:

Cat /usr/bin/yacc
#! /bin/sh
exec '/usr/bin/bison' -y "$@"

We probably should change the check to:

if [ -h /usr/bin/yacc ]; then
  echo "/usr/bin/yacc -> `readlink -f /usr/bin/yacc`";
elif [ -x /usr/bin/yacc ]; then
  echo yacc is `/usr/bin/yacc --version | head -n1`
else
  echo "yacc not found"
fi
