Some/most of the samples/tools throw and error, e.g.:
LLVM ERROR: Cannot select: 0x56049b79dcb0: ch,glue = BPFISD::CALL 0x56049a93ad60, TargetExternalSymbol:i64'__stack_chk_fail'
0x56049b391500: i64 = TargetExternalSymbol'__stack_chk_fail'
In function: waker
bcc-stack-protector.patch adds -fno-stack-protector to the CFLAGS
which fixes this error.
