[FYI] {master} hacking: simplify documentation of bootstrapping process

[Stefano Lattarini]

* HACKING (Working with git): Do not suggest that, to ensure the
bootstrapping process is performed with the latest autotools, the
developer could explicitly pass $AUTOCONF and $AUTOM4TE in the
environment to the ./bootstrap and ./configure invocations: that
is a little tricky and quite fragile.  Instead, suggest to just
put modern-enough version of the autotools early in PATH.

   automake and use it to generate those files.  Be sure to have the

-  not installed as "autoconf", pass it explicitly (along with the
-  accompanying "autom4te") when calling 'bootstrap' and 'configure'.
-  For example:
-    $ AUTOCONF=autoconf2.68 AUTOM4TE=autom4te2.68 ./bootstrap
-    $ ./configure AUTOCONF=autoconf2.68 AUTOM4TE=autom4te2.68
+  latest stable version of Autoconf installed and available early
+  in your PATH.
 
 * Dependent files aclocal.m4, configure and Makefile.in in all
   directories should be up to date in the git repository, so that
