Ok, backporting the Makefile fixes resolves this issue. But perf still
fails to build for me due to some futex errors, which is odd, do you see
that too?
Compilation fails only for modern glibc, like in ubuntu 18.04 bionic.
Xenial 16.04 and precise 12.04 are fine.
I've bisected to indirect fix in linux 4.8
commit cec07f53c398f22576df77052c4777dc13f14962
("perf tools: Move syscall number fallbacks from perf-sys.h to tools/arch/x86/include/asm/")
To 4.4.y it applies clearly.
thanks,
