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"
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.
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).

config BUILD
string
prompt "Build system tuple"

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 tuple"
default ""
depends on NATIVE || CANADIAN
help
Canonical name of the machine running the toolchain.
config HOST_CC
string
prompt "Cross-compiler prefix for host system"

depends on NATIVE || CANADIAN
help
C compiler targeting the host system.
config TARGET_CC

default "${CT_TARGET}-"

help
