The hand-rolled configure script, for multiple options (selinux,mnl,elf), sets
a variable as well as modifying CFLAGS & LDLIBS.

If config.mk is later amended to disable a feature, the CFLAGS/LDLIBS tweaks
are still in place.

Push the CFLAGS/LDLIBS changes into new conditional Makefile code, so that they
are only passed when correctly needed.

Prior Gentoo testcase for reproduction:
USE=minimal ebuild ... compile.
- Linking with libbsd, libelf, libmnl & libcap based only on presence.
- Links based on libselinux based only on presence.
