I did just this in one project. I used luac.exe during the build to
compile "builtin.lua" into bytecode, and then I converted the bytecode
into a C-constant in "builtin.c" which was then compiled into the
program, and run with "lua_dostring". Back then I actually had some
problems with lua_dostring and compiled bytecode, so it could
optionally skip the compile step and just throw the source in
there. However, that was long ago.

All it required was:

1) The luac executable
2) a simple program which read in a file and output 
   a c-file with a c-constant containing the data.
   (i.e.   char builtin_data[] = { xx,yy,zz ...}; )
   I wrote this in lua as well.
3) a few lines in the makefile
