The problem with these two systems in question is that they are
now mostly dead.  I cannot test backing it out on these systems
because they are now mostly dead: both cc(1) and make(1) are
linked statically.

$ hostname
beast.freebsd.org
$ ldd /usr/bin/cc /usr/bin/make
ldd: /usr/bin/cc: not a dynamic executable
ldd: /usr/bin/make: not a dynamic executable

I suspect TLS changes very much because every static binary dumps
a core now:

$ /bin/ls /dev/null
/dev/null
$ file /rescue/ls
/rescue/ls: ELF 64-bit LSB executable, Alpha (unofficial), version 1 (FreeBSD), for FreeBSD 6.0, statically linked, stripped
$ /rescue/ls /dev/null
Segmentation fault (core dumped)

I think there's no emergency plan other than to reinstall "base"
on these systems from some older snapshot?
