string "uClibc configuration file to use?"
default "package/uclibc/uClibc-ng.config"
help
Some people may wish to use their own modified uClibc configuration
file and will specify their config file location with this option.
See also docs/README in this package.
If unsure, use the default.
config BR2_UCLIBC_CONFIG_FRAGMENT_FILES
string "Additional uClibc configuration fragment files"
help
A space-separated list of configuration fragment files,
that will be merged to the main uClibc configuration file.

select BR2_TOOLCHAIN_HAS_NATIVE_RPC
help
Enable this option if you want your toolchain to support
RPC (needed for NFS, for example).
config BR2_TOOLCHAIN_BUILDROOT_WCHAR
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).

Enabling this option will compile and install the getconf,
ldconfig and ldd uClibc utilities for the target.
You can save ~32 KiB in target space by disabling them since
they're normally not needed.
