Makefiles during the build process by touching various auto{conf,make}
source files to make them up-to-date. Packages that require regenerating
the configure script and Makefile.in files should make the appropriate
calls to auto{conf,make} in a pre-configure target. This allows the
various targets listed in ${_CONFIG_PREREQ} to modify the generated files
without triggering the GNU auto* tools and having the modifications be
overwritten.
(manually regenerated from patched configure.in) is added, AUTOMAKE_OVERRIDE
is also defined hence custom pre-configure target is removed.
To avoid useless makeinfo run sed.info, version.texi and stamp-vti are added
to AUTOMAKE_PATTERNS (this also fix a hidden and forgotten build dependency on
../../devel/gtexinfo).
While here my email address as maintainer is updated.
