makeinfo is mandatory at least to build a toolchain. Currently,
dependencies.sh doesn't fail if makeinfo is not present and only
displays a message that can easily be lost. The user will then
encounter the issue later, when it is more difficult to understand
what's happening.
So, this patch simply does for makeinfo what the script does for the
other dependencies: bail out if they aren't available.

Document the new generic package infrastructure, and how target/host
packages are handled, both for the generic package infrastructure and
the autotools package infrastructure.
This documentation replaces the documentation that used to be present
at the top of Makefile.autotools.in. Both tutorial and reference
documentation are provided.

autoconf >= 2.64 was broken when /bin/sh is symlinked to dash. This
has been fixed post-2.65 by the commit at
http://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=7f75858f577f11a844781764f30cd42cfe8a5669.
Compared to the original patch, the patch included in Buildroot
manually does the change to the ./configure script itself. Otherwise,
the compilation of host-autoconf would require host-autoconf itself.

Now that the previous commit implemented a generic package
infrastructure, we make the autotools infrastructure inherit from the
generic one so that the code is not duplicated.
The new AUTOTARGETS macro works by defining what should be done at the
configure, build and install steps of a package and then calls the
GENTARGETS macro of the generic package infrastructure.

This new infrastructure allows to write simpler .mk files for packages
not using the autotools as their build system, by factorizing many
common steps (download, extract, patching), and will more easily allow
Buildroot-wide changes in how the packages are handled.
The main macro is called GENTARGETS and works similarly to the
AUTOTARGETS macro that already exists for autotools-based
packages. However, the set of variables to be defined before calling
the macro is different. Refer to the documentation for details.

Commit 09c181f289 added new options
passed to gcc configure to set --with-pkgversion and --with-bugurl, to
gcc >= gcc 4.3. To check this, it was checking that the GCC_VERSION
string does not contain 4.2.
Unfortunately, the test is bogus. It does a findstring on x4.2. (with
a final dot) but compares the result with x4.2 (without the final
dot).
The result is that even with 4.2 versions, the test was true, leading
--with-pkgversion and --with-bugurl being passed to gcc's configure
script.

This patch fixes the prctl syscall for the AVR32 architecture, since this
architecture assumes you handle varargs in a proper way, always.
