I'm not drawing a correlation between this and unrelated coredumping processes.

Don't make delete-old-lib unless you have it moved off to compat
directories, or have rebuilt everything using the new libarchive.

truss the binaries to figure out exactly what's going wrong.

A lot of this lost effort could be avoided (like others have posted on
the list more than once), by having a centralized package distribution
server, and by having VMs or jails and keeping snapshots with
pre-upgrade state on the package building machine to avoid "dead in
the water scenarios" like you're in right now.

I ran into this issue too a little while ago. I basically gave up on
recovering a VM and nuked and repaved it using a LiveCD with a chroot,
some cp -p'ing, etc. But yes.. it would be nice if I could have
recovered the system at least with a static toolchain: cc, binutils
[equivalent], mtree, install, etc.

service ldconfig start ?

    Simply put: fix your infrastructure (as this isn't the first time
you have complained about infrastructure issues on the MLs). A lot of
these issues should not be issues if you set up your infrastructure
properly to deal with building things only once, backup packages
before installation, you had snapshots of your system, etc. This will
help you avoid administration pain, and hopefully will result in less
duplicated work.
