[RP] Please add AM_MAINTAINER_MODE to configure.in

[Bernhard R. Link]

It would be really nice to have AM_MAINTAINER_MODE in the
configure.in. With this added make will only regenerate
Makefile.in, configure and all this stuff, when an explicit
--enable-maintainer-mode is given to ./configure. This way
it does not always havoc, when timestamps go bad, the
wrong (or none) autotools are installed and so on.

Hochachtungsvoll,
        Bernhard R. Link
