I think that you misunderstood that README a little. The case is when
the file epoll.h is absent at the system. But when it presents (for
test-building we use a gentoo distro which has the file at
$gentoo/usr/include/sys/epoll.h) the test binary should be built
by default (from the corresponding Makefile):
-----
LIBC_HAS_EPOLL := $(shell echo '\#include <sys/epoll.h>' | $(CC) -E - &> /dev/null && echo yes)
ifeq ($(LIBC_HAS_EPOLL),yes)
CFLAGS += -DLTP_EPOLL_USE_SYS_LIBC
else
CFLAGS += -I. -DLTP_EPOLL_USE_LIB
LDLIBS += -lepoll
endif
-----

I read this code like "if there is a system epoll, then use it, else
use the lib which should be downloaded".
