Thank you,

gmake CC=clang LDFLAGS="-lc++abi -lpthread"
indeed works. (It would be great if it worked out of the box, but this is
still a lot better than nothing.)

autotool => out of the book

The issue is that clang (default compiler in openbsd) needs that LDFLAGS
for luajit, gcc no.
I know that LIBLUAJIT_LDEXTRA  can used because I have  done it on my local
openbsd VM

I think we  dont share a fundamental point here: I think we should provide
binaries.
The source is of course  available for all those that want to adapt.
Once we have a "texlive.*build successful" , nothing else to say.
