config USE_SYSROOT

    bool

    prompt "Use sysroot'ed toolchain"

    default y

    help

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

      prefix/target/sys-root/lib and prefix/target/sys-root/usr/lib

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

      *

      * Unless you realy know you need that, leave it empty!

      *

      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}/sys-root

config SHARED_LIBS

    bool

    prompt "Build shared libraries"

    depends on ! BARE_METAL

    default y

    help

      Say 'y' here, unless you don't want shared libraries.

      You might not want shared libraries if you're building for a target that

      don't support it (maybe some nommu targets, for example, or bare metal).

config TARGET_VENDOR

    string

    prompt "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 (unkown) if you don't know better.

config TARGET_ALIAS_SED_EXPR

    string

    prompt "Target 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 "Target 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).

    default ""

    help

      If you have your *build system* tools in a weird location, and/or

      they have an unusual prefix, enter it here.

      Usually, you should leave that empty!

      Eg.:

        If your *build* gcc is /opt/build-tools/bin/weird-gcc then you

        should enter:

            /opt/build-tools/bin/weird-

        If your *build* gcc is /opt/build-tools/bin/weird-gcc and

        /opt/build-tools/bin is in your PATH, you should enter:

            weird-

        If your *build* gcc is /opt/build-tools/bin/gcc then you

        should enter (do not forget to add the trailing '/'):

config BUILD_SUFFIX

    string

    prompt "|  Tools suffix (READ HELP!)"

    default ""

    help

      If your *build system* tools have an unusual suffix, enter it

      here.

      Usually, you should leave that empty!

      Eg.:

        If your 'default' gcc is gcc 4.3.1, but you also have gcc-3.4.2

        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.
