I am just adding that only lua*tex binaries don't work with the 
libc-2.27.so system. Other TL pretest binaries (tex, pdftex, xetex and 
probably all others) work.

I am not able to explain this. Maybe it is something with lua library 
used during bulid? But luatex -credits gives absolutely the same result 
with binary from build farm and from LT pretest. No versions difference 
of used libraries.
