Sorry, this is not root cause of this problem: no 
libsecurityselinuxhelper.so generated.
The macro HAVE_SELINUX_LXC_CONTEXTS_PATH can handle this no 
selinux_lxc_contexts_path problem.

Then I checked the tests/Makefile.am:
  936 if WITH_SECDRIVER_SELINUX
  937 if WITH_ATTR
  938 if WITH_TESTS
  939 noinst_LTLIBRARIES += libsecurityselinuxhelper.la
  940 else ! WITH_TESTS
  941 check_LTLIBRARIES += libsecurityselinuxhelper.la
  942 endif ! WITH_TESTS

The libsecurityselinuxhelper.la is surrounded by the macro WITH_ATTR,
so if there is no WITH_ATTR defined, libsecurityselinuxhelper.so will 
not be created.

The ad-hoc solution is install libattr-devel, and re-configure.

Best wishes,
