tests: avoid a spurious failure on NetBSD

* t/tags-pr12372.sh (configure.ac): AC_SUBST the LINK variable to a
dummy invocation, to avoid possible errors from make or the linker;
errors we do not care about in the least in this test.
(Makefile.am, sub/Makefile.am): Remove LINK definitions; simply
inherit that in configure.ac.
