In "bootstrap" it says:

  # We don't need intl, so remove it.
  # Remove aclocal.m4 too, so that it gets rebuilt.

"aclocal.m4" is a dependency for "configure".

I've never had much motivation to try to understand Bison's bootstrap 
script, so I'll leave it up to someone else to explain why "aclocal.m4" 
needs to be rebuilt.  In the meantime, I wouldn't worry about it.
