I agree there is a problem, but unfortunately this solution will break
external toolchains and crosstool-ng toolchains that use glibc or
eglibc. Those toolchains have NPTL support, but BR2_PTHREADS_NATIVE is
not defined when using such toolchains.

I guess the real solution would be something like:

config BR2_TOOLCHAIN_HAS_NPTL
	bool

and then for internal backend, select this option is
BR2_PTHREADS_NATIVE is enabled. For external backend, select this
option when glibc/eglibc is used, and add an option when the uClibc
library is used. Some similar solution must be found for the
crosstool-NG backend.

Regards,

Thomas
