[Buildroot] [PATCH v2,1/1] domoticz: depends on NPTL

[Fabrice Fontaine]

boost 1.66 uses pthread_condattr_setclock in
boost/asio/detail/impl/posix_event.ipp.

Boost is mostly a header-only library, in particular the asio stuff.
There are sub-options for the parts of Boost that are not purely
headers, but there are not any sub-options for the parts of Boost that
are just headers.

So, the options are either to add sub-options to Boost, or to make
Boost as a whole only available on NPTL toolchains. The latter is a bit
annoying as it would mean adding this dependency to all Boost reverse
dependencies, even those not using asio.

So, instead of updating boost, add a dependency to
BR2_TOOLCHAIN_HAS_THREADS_NPTL to domoticz. This is the best solution
that can be done today. It's not perfect, but it's good enough.
