build: reconfigure automatically if configure.ac changes
This provides a reduced but still useful sibling of the Automake's "automatic Makefile rebuild" feature. It's important to note that we take care to enable the new rules only if the tree that has already be configured with './configure', so that users relying on manual configuration won't be negatively impacted.
