This worked. Pffff. :-)
# /rescue/cp /libexec/ld-elf.so.1 /var/tmp/

# /rescue/cp  
/.zfs/snapshot/auto-2016-12-30_20.00.hourly/libexec/ld-elf.so.1 /libexec/
cp: /libexec/ld-elf.so.1: Operation not permitted

# /rescue/chflags -h noschg /libexec/ld-elf.so.1

# /rescue/cp  
/.zfs/snapshot/auto-2016-12-30_20.00.hourly/libexec/ld-elf.so.1 /libexec/

I will try a clean build now. This will take hours and hours on my laptop  
compiling clang, so I'll see in the new year if others experience the same  
ld-elf problem before I installworld again.

Regards and happy new year,
Ronald.
