Doing this causes more trouble than it is worth regarding cyclic
dependencies. It should not be needed after cleaning up MACHINE=host
builds in r291324.

The main problem was bitrot after elftoolchain being swapped in for the
GNU toolchain.
This also reworks how the list of 'host allowed' libraries is determined
to only allow INTERNALLIBs, which is needed for libelftc to come in.
For usr.bin/readelf use the same hack, as libelf and libdward, to bring in
the needed sys/ headers for host builds. This has not yet been a problem due
to readelf not being built as a host tool in buildworld. This is possible
in the meta build though when building the toolchain.

This allows most of the build to simply consider MK_META_MODE
Update to latest dirdeps.mk so we can do:
make -f dirdeps.mk bin/cat.i386

This is converting the path usr/share/tmac.*stage to something else, but
nothing ever installs or reads from such a path. They might look in
stage.*usr/share/tmac, but that's not what this is matching. Additionally
the .dirdeps match all of the tmac files back to gnu/usr.bin/groff/tmac
fine.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

By moving META_MODE bits from local.sys.mk, they are easier
to skip when MK_META_MODE=no
Update some filters to cope with sync from head.
If buildworld etc or WITHOUT_META_MODE disable all the META_MODE
related options.
