      Use the 'shinny new' sysroot feature of gcc: libraries split between

      prefix/target/sysroot/lib and prefix/target/sysroot/usr/lib

      You definitely want to say 'Y' here. Yes you do. I know you do. Say 'Y'.

    help

      Enter the base name of the sysroot directory. Usually, this simply

      is 'sysroot' (the default) or 'sys-root'.

      You are free to enter anything here, except for spaces, and '/'

      (see SYSROOT_DIR_PREFIX, below). If you leave this empy, then the

      default 'sysroot' is used.

      This string will be interpreted as a directory component to be added

      to the sysroot path, just before the actual sysroot directory.

      In fact, the sysroot path is constructed as:

        ${CT_PREFIX_DIR}/${CT_TARGET}/${CT_SYSROOT_DIR_PREFIX}/${CT_SYSROOT_NAME}

    help

      Build static host binaries.

      If you wish to move the toolchain to another host, and you are not

      confident that this host has the required versions of system libs, then

      you can say 'Y' here, and all the host tools will be linked staticaly.

      The impacted tools are:

        - the GNU binutils

        - the cross-gdb

      The default is 'N', to build dynamicaly-linked host binaries.

      NOTE: this has no connection to whether the target libraries will be

      dynamic or static. This only applies to the tools themselves.

config TOOLCHAIN_PKGVERSION

    string

    prompt "Toolchain ID string"

    default "crosstool-NG-${CT_VERSION}"

    help

      Specify a string that identifies your package. You may wish to include

      a build number or build date. This version string will be included in

      the output of gcc --version, and also in binutils, eglibc, gdb and

      gdbserver.

      This is passed to the configure flag --with-pkgversion.

config TOOLCHAIN_BUGURL

      Specify the URL that users should visit if they wish to report a bug.

config TARGET_VENDOR

    string

    default "unknown"

    help

      Vendor part of the target tuple.

      A tuple is of the form arch-vendor-kernel-system.

      You can set the second part, vendor, to whatever you see fit.

      Use a single word, or use underscores "_" to separate words.

      Use neither dash nor space, as it breaks things.

      Keep the default (unknown) if you don't know better.

config TARGET_ALIAS_SED_EXPR

    string

    prompt "Tuple's sed transform"

    default ""

    help

      Normaly, you'd call your toolchain components (especially gcc) by

      prefixing the target tuple followed by a dash and the component name

      (eg. armeb-unknown-linux-uclibc-gcc).

      You can enter here a sed expression to be applied to ${CT_TARGET} to

      create an alias for your toolchain.

      For example, "s/${CT_TARGET_VENDOR}/foobar/" (without the double quotes)

      will create the armeb-foobar-linux-uclibc alias to the above-mentioned

      toolchain.

      You shouldn't need to enter anything here, unless you plan to manually

      call the tools (autotools-based ./configure will use the standard name).

config TARGET_ALIAS

    string

    prompt "Tuple's alias"

    default ""

    help

      Normaly, you'd call your toolchain components (especially gcc) by

      prefixing the target tuple followed by a dash and the component name

      (eg. armeb-unknown-linux-uclibc-gcc).

      You can enter a shortcut here. This string will be used to create

      symbolic links to the toolchain tools (eg. if you enter "foo-bar" here,

      then gcc for your toolchain will also be available as "foo-bar-gcc" along

      with the original name).

      You shouldn't need to enter anything here, unless you plan to manually

      call the tools (autotools-based ./configure will use the standard name).

        should enter:

        installed as gcc-3.4, then you should enter:

            -3.4

      It can happen that some of the tools have a suffix, when others

      don't, eg. you can have 'gcc-3.4' and 'ar'. crosstool-NG accounts

      for that by checking the tools without the suffix in case it can

      not find some of the tool.
