+ The ports addon contains some architecture ports that are not available

+ help
+ Let ./configure decide what minimum kernel version glibc/eglibc
+ will be able to run against.
+
+ This will inclde legacy compatibility code for older kernels in
+ the C library, thus ensuring that it will run on a large number
+ of old kernels.
+
+ The minimum kernel version supported will be dependent upon the
+ target you build for. For example:
+ alpha*-*-linux-gnu Requires Linux 2.6.9 for NPTL
+ sh[34]-*-linux-gnu Requires Linux 2.6.11
+ powerpc* Requires Linux 2.4.19
+ arm*-*-linux-*gnueabi Requires Linux 2.6.16
+
+config LIBC_GLIBC_KERNEL_VERSION_AS_HEADERS
+ bool
+ prompt "Same as kernel headers (default)"
+ help
+ Normaly, you'll want glibc/eglibc to run against the same kernel
+ version as the one used for the headers.
+
+ This is the default.
+
+ If enabled, crosstool-ng will use the chosen version of kernel
+ headers for the glibc minimum kernel version supported, which is
+ what gets passed to "--enable-kernel=" when configuring glibc.
+
+ Enabling this will ensure that no legacy compatibility code for
+ older kernels is built into your C libraries, but it will
+ be unable to run on kernel versions older than whichever kernel
+ headers version you've built the toolchain for.
+
+ If you know for sure that your toolchain will never need to build
+ applications that will run under a kernel version older than your
+ chosen kernel headers version (CT_KERNEL_VERSION), you can choose
+ "y" here.
+
+config LIBC_GLIBC_KERNEL_VERSION_CHOSEN
+ bool
+ prompt "Specific kernel version"
+ help
+ Specify the earliest Linux kernel version you want glibc to
+ include support for. This does not have to match the kernel
+ headers version used for your toolchain. This controls what is
+ passed to the "--enable-kernel=" option to the glibc configure
+ script.
+
+ If you want to be able to statically link programs with your
+ toolchain's C library, make sure this kernel version is lower than
+ all kernels you wish to support to avoid "FATAL: kernel too old"
+ errors. The higher the version you specify, the less legacy code
+ will be built into libc.
+
+ Most people can leave this at the default value of "2.6.9".
+
+if LIBC_GLIBC_KERNEL_VERSION_CHOSEN

+ string
+ prompt "Minimum kernel version to support"
+ default "2.6.9"
+ help
+ Enter here the lowest kernel version glibc/eglibc will be able to
+ run against.
+
+ The minimum kernel version supported will be dependent upon the
+ target you build for. For example:
+ alpha*-*-linux-gnu Requires Linux 2.6.9 for NPTL
+ sh[34]-*-linux-gnu Requires Linux 2.6.11
+ powerpc* Requires Linux 2.4.19
+ arm*-*-linux-*gnueabi Requires Linux 2.6.16
+
+ Note that no sanity check is performed by crosstool-NG to ensure
+ that the value you enter here is appropriate for your target.
