_csu_finish() to _libc_preinit(), which is an .init_array function
in shared libc (and mark it INITFIRST) or a .preinit_array function
in static libc, grabbing the _dl_cb callback there from ld.so.  Then
in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's
startup bits before main() gets control.
Other cleanups this permits:
- move various startup structures into .data.rel.ro
- the dl* stubs in libc can be strong and call the callbacks provided
via _dl_cb
- no longer need to conditionalize dlctl() calls on presence of _DYNAMIC

For now, this also still uses the existing realpath implmentation
and emits a syslog if we see differening results. Once we have run
with that for a little while we will remove the old code

counterparts but return memory in pages marked MAP_CONCEAL and on
free() freezero() is actually called.

allocate pages, don't call abort() because of corefile data leakage
concerns, but simply _exit().  The reasoning is _rs_init() will only
fail if someone finds a way to apply specific pressure against this
failure point, for the purpose of leaking information into a core which
they can read.  We don't need a corefile in this instance to debug that.
So take this "lever" away from whoever in the future wants to do that.
