Fabrice Fontaine e553f46d1d libmad: needs autoreconf 
libmad uses a very old configure script.

When the toolchain lacks C++ and the build machine lacks /lib/cpp, this
old configure script fails because it can't find a C++ preprocessor that
is valid:

    checking for arm-buildroot-linux-uclibcgnueabi-g++... no
    checking whether we are using the GNU C++ compiler... no
    checking whether no accepts -g... no
    checking dependency style of no... none
    checking how to run the C++ preprocessor... /lib/cpp
    configure: error: C++ preprocessor "/lib/cpp" fails sanity check
    See `config.log' for more details.

This is yet another case that was tentatively fixed by bd39d11d2e
(core/infra: fix build on toolchain without C++), further amended by
4cd1ab1588 (core: alternate solution to disable C++).

However, this only works on libtool scripts that are recent enough, and
thus we need to autoreconf to get it.

We also need to patch configure.ac so that it does not fail on the
missing, GNU-specific files: NEWS, AUTHORS, and Changelog.

README 

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
