Update to mk-20110505

    2011-05-04  Simon J. Gerraty  <sjg@bad.crufty.net>

        * install-mk (MK_VERSION): bump version to 20110505
          first release including meta mode makefiles

    2011-05-02  Simon J. Gerraty  <sjg@bad.crufty.net>

        * meta.stage.mk: add STAGE_AS_SETS and stage_as
          for things that need to be staged with different names.

    2011-05-01  Simon J. Gerraty  <sjg@bad.crufty.net>

        * meta.stage.mk: add notion of STAGE_SETS
          so a makefile can stage to multiple dirs

    2011-04-03  Simon J. Gerraty  <sjg@bad.crufty.net>

        * rst2htm.mk: convert rst to s5 (slides) or plain html depending
          on target name. 

    2011-03-30  Simon J. Gerraty  <sjg@bad.crufty.net>

        * install-mk (MK_VERSION): bump version to 20110330

    2011-03-29  Simon J. Gerraty  <sjg@bad.crufty.net>

        * sys.mk (_DEBUG_MAKE_FLAGS): use indirection so that
        * DEBUG_MAKE_FLAGS0
          can be used to debug level 0 only and DEBUG_MAKE_FLAGS for the rest.
        * sys.mk: re-define M_whence in terms of M_type.
          M_type is useful for checking if something is a builtin.

        * meta.stage.mk: add stage_symlinks and leverage StageLinks for
          stage_libs 

    2011-03-10  Simon J. Gerraty  <sjg@bad.crufty.net>

        * dirdeps.mk: correct value for _depdir_files depends on
          .MAKE.DEPENDFILE 
          Add our copyright - just to make it clear we have frobbed this
          quite a bit.
          DEP_MACHINE needs to be set to MACHINE each time, if using only
          Makefile.depend (cf. Makefile.depend.${MACHINE})

        * meta.stage.mk: meta mode version of staging

        * init.mk, final.mk: include local.*.mk to simplify customization

    2011-03-03  Simon J. Gerraty  <sjg@bad.crufty.net>

        * auto.obj.mk: just because we are doing mk destroy, we should
          still set .OBJDIR correctly if it exists.

        * install-mk (mksrc): do not exclude meta.sys.mk

    2011-03-01  Simon J. Gerraty  <sjg@bad.crufty.net>

        * host-target.mk: set/export _HOST_ARCH etc separately,
          catch junk resulting from uname -p, so we can find sys/Linux.mk
          correctly.

    2011-02-18  Simon J. Gerraty  <sjg@bad.crufty.net>

        * meta.sys.mk: throw an error if /dev/filemon is missing and we
          expected to be updating Makefile.depend*

    2011-02-14  Simon J. Gerraty  <sjg@bad.crufty.net>

        * install-mk (MK_VERSION): bump version to 20110214
        * meta.subdir.mk: add support for -DBOOTSTRAP_DEPENDFILES

    2010-09-25  Simon J. Gerraty  <sjg@bad.crufty.net>

        * meta.sys.mk: not valid for older bmake

    2010-09-24  Simon J. Gerraty  <sjg@bad.crufty.net>

        * install-mk (MK_VERSION): bump version to 20100919
        include dirdeps.mk et al from Juniper Networks, 
        for meta mode - requires filemon(9).
        * sys.mk, subdir.mk: Add hooks for meta mode.
        we do this as meta.sys.mk, meta.autodep.mk and meta.subdir.mk
        to make turning it on/off simple.

    2010-06-16  Simon J. Gerraty  <sjg@bad.crufty.net>

        * install-mk (MK_VERSION): bump version to 20100616
