Extract the config files related stuff from the kconfig stuff
- create config/config.mk, with all the config.gen/ rules
- the only common points between config files and configurators:
- the top-level config file to include, stored in KCONFIG_TOP
- the config_file rules, which makes config files available to configurators
- dependency-files are renamed from %.d to %.dep (.d is reserved for directories)
- a few eye-candy here and there

     5 config FORCE_EXTRACT

     6     bool

     7     prompt "Force extractions"

     8     default n

     9     help

    10       Force extraction of already exctracted tarballs.

    11       

    12       Usefull if you suspect a previous extract did not complete (eg. broken

    13       tarball), or you added a new set of patches for this component.

    14 

    15 config OVERIDE_CONFIG_GUESS_SUB

    16     bool

    17     prompt "Override config.{guess,sub}"

    18     default y

    19     help

    20       Override tools' versions of config.guess and config.sub with the ones

    21       from crosstool-NG. This means that all instances of config.guess and

    22       config.sub in gcc, binutils, glibc, etc... will be replaced.

    23 

    24       Most of the time, the versions of those scripts found in packages are old

    25       versions, thus lacking some target definitions. This is the case for

    26       uClibc-based tuples in old versions of gcc and gdb, for example.

    27 

    28       Also, doing so will guarantee that all components have the same tuples

    29       definitions for your target, and not diverging ones.

    30 

    31       You can update the ones provided with crosstool-NG by first running:

    32         ct-ng updatetools

    33       in the directory where you want to run crosstool-NG prior to the build.

    34 

    35 config ONLY_EXTRACT

    36     bool

    37     prompt "Stop after extracting tarballs"

    38     default n

    39     help

    40       Exit after unpacking and patching tarballs.

    41       

    42       Usefull to look at the code before doing the build itself.
