Subject: Makefile: Use default rule to link pack_cis
Forwarded: https://git.kernel.org/pub/scm/utils/cis-tools/cis-tools.git/commit?id=6d80f5fe05be80aa86e3af07a8558d4c283e45c1

Currently we define our own rule to build pack_cis, which does not
include CFLAGS and LDFLAGS in the command.  The only special thing
about pack_cis is that it uses floating-point function so needs the
-lm option (unlike dump_cis).

Intead of defining our own rule for pack_cis, just define LDLIBS
so that the default rule will work.
