thread_func in builtin-sched.c has an internal loop and
never returns. The only return from this thread are
BUG_ON calls in case return values are not 0.
The compiler on Android complains that the function
needs to return a non-void value. Adding the noreturn
function attribute to fix this error.
Error in Android:
target C: perf <= builtin-sched.c
hardware/intel/linu/tools/perf/builtin-sched.c: In function 'thread_func':
hardware/intel/linux/tools/perf/builtin-sched.c:476: error: no return
statement in function returning non-void
