bool
prompt "old/stable"
help
From the uClibc config option help:
There are two versions of linuxthreads. The older (stable) version
has been in uClibc for quite a long time but hasn't seen too many
updates other than bugfixes.
config LIBC_UCLIBC_LNXTHRD_NEW
bool
prompt "new"
help
From the uClibc config option help:
The new version has not been tested much, and lacks ports for arches
which glibc does not support (like frv, etc...), but is based on
the latest code from glibc, so it may be the only choice for the
newer ports (like alpha/amd64/64bit arches and hppa).

help
Say y if you want uClibc to support localisation.
Note that seems to be broken on recent uClibc releases.

help
If you see issues with using pre-generated locales data,
you can try switching this off.
If so, please report the issue, so we can default this
to off if too many people complain.
config LIBC_UCLIBC_IPV6
bool
prompt "Add support for IPv6"
help
Say y if you want uClibc to support IPv6.
config LIBC_UCLIBC_WCHAR
bool
prompt "Add support for WCHAR"
help
Say y if you want uClibc to support WCHAR.
Maybe this is needed, if you're building a C++-Compiler
config LIBC_UCLIBC_FENV
bool
prompt "Add support for fenv.h"
default y if ARCH_x86
help
fenv.h provides functions to control the floating point environment,
such as rounding mode, exceptions...
For some architectures, fenv.h is incomplete, so is not installed
by default. x86 is known to have a rather complete fenv.h, so it is
installed by default only for x86.
If you need fenv.h on other architectures, say 'y' here, but you may
encounter some issues.
config LIBC_UCLIBC_RPC
bool
prompt "Add support for RPC"
help
Enable support for remote procedure calls (RPC) in uClibc.
if ARCH_arm
config LIBC_UCLIBC_USE_GNU_SUFFIX
bool
default y
prompt "Use -uclibcgnueabi suffix"
help
Depending on where the resulting toolchain will be used, you may need
to tweak the "system" part of the target tuple. Buildroot prefers
to have arm-*-linux-uclibcgnueabi; OpenEmbedded prefers
arm-*-linux-uclibceabi. Other tools seem to either accept both, or
don't care about the suffix.
