You'd rather need to link with this:
libdhcp_user_chk_la_LIBADD +=
$(top_builddir)/src/lib/dhcpsrv/libkea-dhcpsrv.la
In most cases you'd also need to link with libkea-dhcpsrv.la
dependencies which you can find it its Makefile.am.
As for the automake error it seems to me that you're missing
automake-1.14. Perhaps you have some different version? automake-1.15?
Maybe go to Kea root directory and run autoreconf --install &&
./configure ... && make
again.
