[PATCH 1/3] build: require Autoconf >= 2.62 and Automake >= 1.11.1

[Stefano Lattarini]

Older versions of those tools should be considered fully obsolete.
Also, GNU make already requires Gettext >= 0.18.1, which has been
released six months after Automake 1.11.1 and two years after
Autoconf 2.62; so the new requirement shouldn't be problematic
for people already bootstrapping GNU make from the Git repository.

* configure.ac (AC_PREREQ): Require Autoconf 2.62 or later.
(AM_INIT_AUTOMAKE): Require Automake 1.11.1 or later (1.11 had
some serious bugs, and should not be used).
