As our architecture support expands to a number of architectures that do not implement NPTL threading, and the number of packages that depend on NPTL specific features, it has become necessary to be able to know whether the toolchain has NPTL support or not. This commit adds a new BR2_TOOLCHAIN_HAS_THREADS_NPTL hidden Config.in option that allows packages to know whether NPTL is available or not. This hidden option is: * Automatically enabled when glibc/eglibc or musl toolchains are used, either internal or external. * Automatically enabled when an internal uClibc toolchain with NPTL support is configured. It is left disabled otherwise for internal uClibc toolchains. * Configured according to a visible Config.in option for custom external uClibc toolchains. [Peter: factor _EXTERNAL_HAS_THREADS in single if as suggested by Arnout] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

See 'locale -a' on your host for a list of locales available

the target file system for available locales.
