I don't think there's a standard. FWIW, I use .lbc but .luo sounds
nicer.

This works very well. I have a 'shell' along the lines of lua.c which
loads three or four byte-code libraries either from internal byte arrays
or from external .lbc files.

Just watch out for strlen() and friends ... there's a function in lua.c
that calls this before loading the buffer. That's fine if the string is
text but if it's precompiled byte code strlen() just won't cut the
mustard.
