Add the support of asking for extra modules or bundles of modules

to be fetched from the CPAN and installed as a part of the Perl
build process.  None of this installation is yet really done;
only the list is asked, and saved away in extras.lst for
the build and installation process to worry about later.

+Perl can be built with extra modules or bundles of modules which
+will be fetched from the CPAN and installed alongside Perl.
+
+Notice that you will need access to the CPAN; either via the Internet,
+or a local copy, for example a CD-ROM or a local CPAN mirror.  (You will
+be asked later to configure the CPAN.pm module which will in turn do
+the installation of the rest of the extra modules or bundles.)
+
+Notice also that if the modules require any external software such as
+libraries (the libz library for the Compress::Zlib module, for example)
+you *NEED* to have any such external software already installed, this
+configuration process will not install such things for you.
+
+If this doesn't make any sense to you, just accept the default '$dflt'.

+Please list any extra modules or bundles to be installed from CPAN,
