libs/libc/pthread/pthread_spinlock.c:  Resolve several TODO issues by accessing up_testset() via the boardctl() interface rather than attempting to call it directly.

    configs/boardctl.c, include/sys/boardctl.h:  Add access to architecture-specific up_testset() via boardctl().

    arch/Kconfig's, sched/Kconfig, and include/nuttx/spinlock.h:  Spinlocks are not available unless the architecture supports the up_testset() operation.
