Why is xargs blindly calling /bin/echo?  Wouldn't it just be simpler to
change xargs.c' definition of default_cmd to be "echo" instead of
"/bin/echo" and using execvp instead of execve?  In a compliant
environment, you are guaranteed that echo(1) is on PATH, and calling the
wrong echo because of a non-compliant environment is not really xargs'
concern.  In other words, instead of making it more complex by adding
configure --with-echo, I propose making it simpler by dropping the
hard-coding in the first place.
