libmd: add dependency workaround for r366344

r366344 fixed and reenabled the assembly optimized skein implementation,
but skein_block objects were not being rebuilt in no-clean builds. This
resulted in failing no-clean builds. SKEIN_USE_ASM controls which
routines come from C vs assembly, and with no explicit dependency
r366344's change to SKEIN_USE_ASM did not cause skein_block.{o,pico}
to be rebuilt.

Add a dependency on this Makefile for the skein_block objects. This
dependency is broader in scope than absolutely required (that is, the
skein_block objects will now be rebuilt on any change to this Makefile).
There are ways this could be addressed, but it is probably not worth the
additional effort or testing time to pursue them.

That is, GNU as and Clang's integrated assembler use different multi-

while Clang IAS emits a 10 byte NOP + a 4 byte NOP).

Dependency cleanup hacks are not required, because we do not create
.depend files from GNU as.

For users who have a seperate zfs mount of /usr or /usr/lib, this will
cause dynamic loading failures when attempting to execute zfs mount on
bootup. E.g. the system won't boot.

Including <src.opts.mk> sets SHLIBDIR, so SHLIBDIR?= has no
effect. The other lib/ Makefiles solve this problem by moving the
SHLIBDIR assignment to before .include <src.opts.mk>.

Fix bootstrapping libmd on older systems after r314709.

This follows another fix to bootstrap libmd after r313404. The
MD5FileChunk prototype is needed to build libmd, but it is
only reliably in the src tree's sys/md5.h header. Rather than
polluting the legacy build with this header for the entire build,
just symlink it in here for now as is done in the elftoolchain
build. Libmd is already referencing other src tree headers by
its used of CFLAGS+= ${SRCTOP}/sys/crypto/sha2. This, and
other uses of CFLAGS+= ${SRCTOP}/sys..., may later change to
be in the legacy mechanism.
