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

     3 comment "Build behavior"

     4 

     5 config PARALLEL_JOBS

     6     int

     7     prompt "Number of parallel jobs"

     8     default 1

     9     help

    10       Number of jobs make will be allowed to run concurently.

    11       Set this higher than the number of processors you have, but not too high.

    12       A good rule of thumb is twice the number of processors you have.

    13       

    14       Enter 1 (or 0) to have only one job at a time.

    15 

    16 config LOAD

    17     int

    18     prompt "Maximum allowed load"

    19     default 0

    20     help

    21       Specifies that no new jobs should be started if there are others jobs

    22       running and the load average is at least this value.

    23       

    24       Makes sense on SMP machines only.

    25       

    26       Enter 0 to have no limit on the load average.

    27       

    28       Note: only the integer part of the load is allowed here (you can't enter

    29             0.75 for example).

    30 

    31 config NICE

    32     int

    33     prompt "Nice level"

    34     default 0

    35     range 0 19

    36     help

    37       Renices the build process up.

    38 

    39 config USE_PIPES

    40     bool

    41     prompt "Use -pipe"

    42     default y

    43     help

    44       Use gcc's option -pipe to use pipes rather than temp files when building

    45       the toolchain.

    46 

    47 config CONFIG_SHELL_ASH

    48     bool

    49     prompt "Use 'ash' as CONFIG_SHELL"

    50     default n

    51     help

    52       Use /bin/ash as the shell used by ./configure scripts.

    53       

    54       ./configure scripts make intensive use of calling a sub-shell, and the

    55       traditional bash is slow, whereas ash is faster.

    56       

    57       Saying 'y' here should be safe enough, but some components may not

    58       accept using a shell other than bash (this is most probably true for

    59       old versions). If you have trouble, say 'n' here and see if it fixes it.
