I have to send the patch to upstream TeX Live anyway, so I could just 
copy the luajit author.

I'm not sure; I find that discussion ambiguous.  On the other hand, 
there's no mention of -fexceptions or -funwind-tables in the Makefiles, 
and src/Makefile explicitly says (line 150) that there's probably no 
need to change CFLAGS.
