Log Message:
* Add user-controlled mk.conf variables
	- SHLIBDIR	Location to install shared libraries if ${USE_SHLIBDIR}
			is "yes".  Defaults to "/usr/lib".

	- USE_SHLIBDIR	If "yes", install shared libraries in ${SHLIBDIR}
			instead of ${LIBDIR}.  Defaults to "no".
			Sets ${_LIBSODIR} to the appropriate value.
			This may be set by individual Makefiles as well.

	- SHLINKDIR	Location of shared linker.  Defaults to "/usr/libexec".
			If != "/usr/libexec", change the dynamic-linker
			encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
	libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
	libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
  to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)

The net effect of these changes depends on how the variables are set:

  1.)	If nothing is set or changed, there is no change from the
	current behaviour:
		- Static /bin, /sbin, and bits of /usr/*
		- Dynamic rest
		- Shared linker is /usr/libexec/ld*so

  2.)	If the following make variables are set:
		LDSTATIC=
		SHLINKDIR=/lib
		SHLIBDIR=/lib
	Then the behaviour becomes:
		- Dynamic tools
		- .so libraries used by /bin and /sbin are installed to /lib,
		  with symlinks from /usr/lib/lib*so to -> /lib/lib*so
		  where appropriate
		- Shared linker is /lib/ld*so

  3.)	As per 2.), but add the following variable:
		USE_SHLIBDIR=yes
	This forces all .so's to be instaleld in /lib (with compat
	symlinks), not just those tagged by their Makefiles to be.
	Again, compat symlinks are installed
