rt-tests doesn't build with some "old" toolchains due to missing local syscall number definition for the new kernel deadline scheduler on some architectures. Upsteam added __NR_sched_setattr and __NR_sched_setattr definition only for common architectures (x86, x86_64, arm) and tile if not already defined [1]. Instead of adding missing syscall number, avoid building rt-tests with toolchain compiled with too old kernel headers (i.e !BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_14) At runtime, a 3.14 kernel must be used otherwise these syscall are not available.
