dirdeps.mk and meta.autodep.mk will now look for
Makefile.depend.options
to handle optional dependencies, the work is all done by
dirdeps-options.mk
Also update to latest meta.stage.mk and gendirdeps.mk

Rtld is not compatible with SSP, and since we link libc_pic.a to rtld
to have the basic support like memory and string copy functions, we
have to both carefully limit libc use, and to provide the ssp support
shims. This change makes the libc use in rtld more straighforward but
still limited, and allows to remove the shims, to be done in the next
commit.

build can break when different source files create the same target
files (case-insensitivity speaking). This is the case for object
files compiled with -fpic and shared libraries. The former uses
an extension of ".So", and the latter an extension ".so". Rename
shared object files from *.So to *.pico to match what NetBSD does.

This would otherwise disallow using meta files from a foreign build that
spread them around in directories outside our own .OBJDIR.

dirdeps.mk: move logic to handle -f dirdeps.mk to inside check
for first read of dirdeps.mk
Also fix handling of WITHOUT_DIRDEPS_BELOW
gendirdeps.mk: pass M2D_EXCLUDES to meta2deps
meta.autodep.mk: if we build with nofilemon, leave a cookie to
prevent updating dependencies until cleaned.

This was finding libraries that were installed into DESTDIR/usr/lib,
where DESTDIR is the stage directory, and then adding in usr/lib to
DIRDEPS. Just exclude the STAGE_ROOT if defined.

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.
