Introduce a new EXPERIMENTAL feature: BARE_METAL.
This should ultimately llow to build bare-metal compilers, for targets that have no kernel and no C library.
Move the C library build script to their own sub-directory; introduce an empty build script for bare-metal.
Move the compiler build script to its own sub-directory.
Move the kernel build script to its own sub-directory; introduce an empty build script for bare-metal.
Update the ARM target tuples to enable bare-metal targets.
Add two ARM bare-metal samples.
Add latest Linux kernel versions.

# eglibc options

choice

    bool

    prompt "eglibc version"

config EGLIBC_V_TRUNK

    bool

    prompt "'trunk'"

    help

      Selecting this will export the trunk of the eglibc subversion repository.

config EGLIBC_V_2_5

    bool

    prompt "2.5"

config EGLIBC_V_2_6

    bool

    prompt "2.6"

config EGLIBC_V_2_7

    bool

    prompt "2.7"

config EGLIBC_V_2_8

    bool

    prompt "2.8"

# CT_INSERT_VERSION_ABOVE

# Don't remove above line!

endchoice

config LIBC_VERSION

    string

    default "trunk" if EGLIBC_V_TRUNK

    default "2_5" if EGLIBC_V_2_5

    default "2_6" if EGLIBC_V_2_6

    default "2_7" if EGLIBC_V_2_7

    default "2_8" if EGLIBC_V_2_8

# CT_INSERT_VERSION_STRING_ABOVE

# Don't remove above line!

config EGLIBC_REVISION

    string

    prompt "Revision to use"

    default "HEAD"

    help

      Enter the revision of trunk you want to use.

      Default is HEAD.

      A revision argument can be one of:

          NUMBER       revision number

          '{' DATE '}' revision at start of the date (*)

          'HEAD'       latest in repository

      (*) If you want to use a date, please use ISO-8601 formats if

          at all possible.

config EGLIBC_CHECKOUT

    bool

    prompt "checkout instead of export"

    default y if EGLIBC_V_TRUNK

    default n if ! EGLIBC_V_TRUNK

    help

      By default, the eglibc download will be an export of the subversion

      repository. If you say 'y' here, then the repository will instead be

      checked-out, so that you can update it later.

      Note that crosstool-NG will *not* update your working copy, you will

      have to do that yourself.
