[Buildroot] [PATCH 1/3] package/boost: disable boost-log with bfin uClibc 2014R1 toolchain

[Romain Naour]

pthread_spin_* functions are not implemented in the uClibc used by this toolchain.

In file included from libs/log/src/threadsafe_queue.cpp:33:
./boost/log/detail/spin_mutex.hpp: In constructor ‘boost::log::v2_mt_posix::aux::spin_mutex::spin_mutex()’:
