a950d57c9f LBR, BTM, or BTS records may have incorrect branch "from" information afer an 
EIST transition, T-states, C1E, or Adaptive Thermal Throttling (AAJ122).

This results in sporadic test fails. Disable btrace on those processors.

gdb/
	* common/linux-btrace.c: Include sys/ptrace, sys/types, sys/wait.h,
	and signal.h.
	(linux_supports_btrace): Add kernel and
