configure: use autoconf to generate configure

Create configure.ac, an autoconf script to generate ./configure
This will be needed by a subsequent patch to properly handle
--build and --host, and more tests, when the kconfig stuff will
be installed pre-built.

Crosstool-NG follows the autoconf dance. So, to get you
kick-started, just run:
./configure --help
./configure --help
If you are using a development snapshot, you'll have to
create the configure script, first. Just run:
./bootstrap
You will find the documentation in the directory 'docs'.
Here is a quick overview of what you'll find there:

\`configure' configures crosstool-NG-${VERSION} to adapt to many kind of systems.
USAGE: ./configure [OPTION]...
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--force force configure to continue, even in case
some pre-requisites are missing
Installation directories:
--prefix=PREFIX install files in PREFIX [${PREFIX_DEFAULT}]
--local don't install, and use current directory
By default, \`make install' will install all the files in
\`${PREFIX_DEFAULT}/bin', \`${PREFIX_DEFAULT}/lib' etc. You can specify
an installation prefix other than \`${PREFIX_DEFAULT}' using \`--prefix',
for instance \`--prefix=\${HOME}'.
For better control, use the options below.
Note: options marked as \`ignored' are recognised, but not acted upon, as
they make no sense for crosstool-NG, or they are not implemented yet.
Fine tuning of the installation directories:
--bindir=DIR user executables [PREFIX/bin]
--libdir=DIR object code libraries [PREFIX/lib]
--docdir=DIR info documentation [PREFIX/share/doc]
--mandir=DIR man documentation [PREFIX/share/man]
--infodir=DIR info documentation [DATAROOTDIR/info] (ignored)
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
(ignored)
--sysconfdir=DIR read-only single-machine data [PREFIX/etc] (ignored)
--localstatedir=DIR modifiable single-machine data [PREFIX/var] (ignored)
Program names:
--program-prefix=PREFIX prepend PREFIX to installed program names
--program-suffix=SUFFIX append SUFFIX to installed program names
--program-transform-name=PROGRAM run sed PROGRAM on installed program names
System types:
--build=BUILD configure for building on BUILD [guessed] (ignored)
--host=HOST cross-compile to build programs to run on HOST [BUILD]
(ignored)
Optional Features:
--enable-shared[=PKGS] build shared libraries [default=yes] (ignored)
--enable-static[=PKGS] build static libraries [default=yes] (ignored)
Optional Packages:
--with-install=PATH Specify the full PATH to GNU install
--with-make=PATH Specify the full PATH to GNU make >= 3.80
--with-grep=PATH Specify the full PATH to GNU grep
--with-sed=PATH Specify the full PATH to GNU sed
--with-bash=PATH Specify the full PATH to bash >= 3.0

You can then get rid of crosstool-NG source. Next create a directory to serve
as a working place, cd in there and run:
mkdir work-dir
cd work-dir
ct-ng help
See below for complete usage.
@ -39,8 +41,12 @@ The Hacker's way |
-----------------+
If you go the hacker's way, then the usage is a bit different, although very
simple:
./configure --local
simple. First, you need to generate the ./configure script from its autoconf
template:
./bootstrap
Then, you run ./configure for local execution of crosstool-NG:
./configure --enable-local
make
Now, *do not* remove crosstool-NG sources. They are needed to run crosstool-NG!
