Archive member handling works again
meta mode, treat missing reads as for writes.
Update dirdeps.mk - much improved startup time.
Update meta.stage.mk - avoid ln when chmod required.
This also fixes truncating the path that the links were installed to, which
was most likely going to be the same directory the library was in anyhow.
Let bsd.sys.mk handle SYMLINKS via stage_symlinks. stage_libs continues to
handle the SHLIB_LINK though since it is not a SYMLINKS.
This fixes a race, seen easily in lib/libthr, where libpthread_p.a is created
by both stage_libs and stage_symlinks resulting in 'ln: File exists'.

stage_* targets.
In non-jobs mode we can achieve the same result by simply introducing
the targets in the correct order.
Thus in bsd*.mk we simply add targets to STAGE_TARGETS which we
realize in meta.stage.mk

This fixes staging errors for non-parallel builds that have LINKS.
Creating hardlinks must always happen after the actual files are installed.
The staging code was protected by an .ORDER statement that only affected
parallel -j builds but not non-parallel builds. Fix this by making the
real stage_links.SET (stage_links.links, stage_links.mlinks, etc) targets
depend on the main targets for all of the other possible staging needs. For
example, stage_links.links will depend on stage_as and stage_files, which have
their own dependencies to stage_as.prog or stage_files.prog or stage_files.SET,
which is enough to satistfy the ordering.
Also remove the requirement that symlinks be created last, as they can
safely be made without the source being present unlike hardlinks. This also
fixes symlinks to come before hardlinks as it is possible, in theory, to
hardlink a symlink. This is not actually supported here though.

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.
