 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).

     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.

       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).

       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.
