OK: it can be just this:
timerfd_settime02:	CFLAGS	+= -pthread
timerfd_settime02:	LDLIBS	+= -lrt

because failure in CentOS 6 is different:
timerfd01.c:36: undefined reference to `clock_gettime'
https://api.travis-ci.org/v3/job/657694167/log.txt

Obviously we need autotools check for it (trivial, I can do it before merge).

Kind regards,
Petr
