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'.

config SHARED_LIBS
    bool
    prompt "Build shared libraries"
    default y
    help
      Say 'y' here, unless you don't want shared libraries.
      
      You might not want shared librries if you're building for a target that
      don't support it (maybe some nommu targets, for example, or bare metal).

config TARGET_MULTILIB
    bool
#    prompt "Enable 'multilib' support (EXPERIMENTAL)"
    default n
    help
      Enable the so-called 'multilib' support.
      
      With the same toolchain, and on some architectures, you will be able to
      build big and little endian binaries, soft- and hard-float, etc...
      
      See the gcc configure manual at http://gcc.gnu.org/install/configure.html
      to see what multilib your target supports.
      
      It's preferable for now to build two (or more) toolchains, one for each
      configuration you need to support (eg. one for thumb and one for ARM,
      etc...). You can use the vendor string to diferentiate those toolchains.

config TARGET_VENDOR
    string
    prompt "Vendor string"
    default "unknown"
    help
      Vendor part of the machine triplet.
      
      A triplet 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.
      
      Keep the default (unkown) if you don't know better.

config TARGET_ALIAS
    string
    prompt "Target alias"
    default ""
    help
      Normaly, you'd call your toolchain component (especially gcc) by
      prefixing the target triplet 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).

config BUILD 
    string
    prompt "Build system triplet"
    default ""
    help
      Canonical name of the machine building the toolchain.
      You should leave empty, unless you really now what you're doing.

config CC_NATIVE
    string
    prompt "Native gcc"
    default "gcc"
    help
      The native C compiler.
      
      You can set this to an alternative compiler if you have more than one
      installed (eg. gcc is gcc-4.1.1 and you want to use gcc-3.4.6).
      
      You can leave this empty as well, in which case gcc will be used.

config HOST
    string
    prompt "Host system triplet"
    default ""
    depends on NATIVE || CANADIAN
    help
      Canonical name of the machine running the toolchain.
