Complete de-orbit burn sequence for automake19 and automake110.

Special thanks to Travis Thaxton (travis <at> thax.org) for his recent
kind hardware donation, without which this particular part of the
never-ending autotools work would have taken _considerably_ longer to do.

Autotools update.   Read ports/UPDATING 20100915 for details.

Approved by:    portmgr (for Mk/bsd.port.mk part)
Tested by:      Multiple -exp runs

Reassign the autotools-related ports to a new mailing list,
autotools@FreeBSD.org.  This is for individuals willing to put in
the hard work to generate patches and work with portmgr as we put
them through -exp runs and work through port breakage that they
create.  (A huge number of ports depend on these, so -exp runs are
required.)

Thanks to aDe@ for all the thankless work he's done over the years
to tame these beasts.

Update CONFIGURE_ARGS for how we pass CONFIGURE_TARGET to configure script.
Specifically, newer autoconf (> 2.13) has different semantic of the
configure target. In short, one should use --build=CONFIGURE_TARGET
instead of CONFIGURE_TARGET directly. Otherwise, you will get a warning
and the old semantic may be removed in later autoconf releases.

To workaround this issue, many ports hack the CONFIGURE_TARGET variable
so that it contains the ``--build='' prefix.

To solve this issue, under the fact that some ports still have
configure script generated by the old autoconf, we use runtime detection
in the do-configure target so that the proper argument can be used.

Changes to Mk/*:
 - Add runtime detection magic in bsd.port.mk

Conversion from (now defunct) autoconf-2.61 to autoconf-2.62

Tested by:      exp build run (erwin)

Major autotools-related update:

        automake        1.10   -> 1.10.1
        gettext         0.16.1 -> 0.17
        libtool         1.5.24 -> 1.5.26

Purge 5.x support

Fix automake-1.10 and autoconf-2.61 correctly.

One bad merge out of 25.  Sigh.

Update to the autotools new world order.

Tested by:      numerous package build runs

- Set --mandir and --infodir in CONFIGURE_ARGS if the configure script
  supports them.  This is determined by running ``configure --help'' in
  do-configure target and set the shell variable _LATE_CONFIGURE_ARGS
  which is then passed to CONFIGURE_ARGS.
- Remove --mandir and --infodir in ports' Makefile where applicable
  Few ports use REINPLACE_CMD to achieve the same effect, remove them too.
- Correct some manual pages location from PREFIX/man to MANPREFIX/man
- Define INFO_PATH where necessary
- Document that .info files are installed in a subdirectory relative to
  PREFIX/INFO_PATH and slightly change add-plist-info to use INFO_PATH and
  subdirectory detection.

Fix botched patch, ensuring that automake 1.10 actually uses
autoconf 2.61 like it's supposed to.
