Yes and no.  You can run into trouble if the target machine has a
different version (older OR newer!) of autoconf or automake.  Mostly
this is due to a badly-written macro which is, sadly, rather common.

However, if *no* autotools are detected, updating the or
configure file just doesn't happen, as you suspected.  

You can completely disable these "maintainer rules" in the
*distributed* makefiles via the AM_MAINTAINER_MODE macro.  Look it up
in the automake docs.
