Enter here the crosstool-NG's .config file to use.
To fine-tune your toolchain, you can also call:
make ctng-menuconfig
If unsure, keep the default value.

Enable this option if you want your toolchain to support
files bigger than 2 GB.
config BR2_TOOLCHAIN_CTNG_uClibc_INET_IPV6
bool "Enable IPv6 support"
select BR2_INET_IPV6
help
Enable this option if you want your toolchain to support
IPv6.

help
Enable this option if you want your toolchain to support
RPC (needed for NFS, for example).

bool "Enable WCHAR support"
select BR2_USE_WCHAR
help
Enable this option if you want your toolchain to support
wide characters (i.e characters longer than 8 bits, needed
for locale support).

Enable this option if you want your toolchain to support
localization and internationalization.

C++ language and you want C++ libraries to be installed on
your target system.

help
Enable thread support and select thread implementation. With
glibc, thread support is mandatory but several
implementations are available. With uClibc, thread support
is optional, and when enabled, several implementations are
available. However, not all thread variants work with all
versions of uClibc for all architectures, the "linuxthreads
(stable/old)" may be a working fallback.
