Just run make, the makefile will notice that some of the files are out
of date and re-generate them for you

Personally, I'm in the "remove AM_MAINTAINER_MODE" camp.  The default
behaviour (contrary to a commonly held belief) is to always rebuild when
required, AM_MAINTAINER_MODE disables this and makes you specify
--enable-maintainer-mode to get the rebuild rules.

The automake documentation lists some good arguments towards removing
AM_MAINTAINER_MODE:
