Add AM_MAINTAINER_MODE macro to configure.ac and enable it by default
AM_MAINTAINER_MODE macro adds ability to disable rebuilding build file (Makefile.in, configure, ...) when the source file changes. This is important in the CI where the timestamps could get skewed and that triggers the rebuild on every ./configure run.
